Friends who treat friends badly

Hi everyone!
I have this friend who always claims to be my best friend but she treats me terribly. I can be a very outgoing person who acts like a dork when im in the right mood.
This so called friend often calls me dumb, stupid, and even retarded because of this. She also always tries to force me into doing things that she wants to do without asking me or making sure I even have an interest. I can tell her multiple times that i dont want to do something and she will repeatedly say things like "yes you will" or if I have something else I want to do "I wont let you." If I don't go to things she wants me to, I'll get a nasty text from her the next day. For example the one I got this morning after I told her I wasn't going to go to an event that was yesterday, was, and I quote "thanks for not showing up yesterday. That was really great." After I told her multiple times "NO."
She even signed me up for it without permission.
I am someone who suffers from depression and low self-esteemso when she does these things, I feel worse about myself.
She walks all over me all the time and I have no idea how to handle it. Right now I've kinda got her cut off by just ignoring her. I am a very nice person who hates to be mean so I don't know what to do in order to end this.
Does anyone else have this problem?

I don't have this problem but you're doing the right thing. Keep ignoring her and cutting her off. You don't deserve that kind of treatment from a "friend" who is supposed to be your best friend. I hope you find a friend worthy of your time and you start feeling better about yourself.

I have a friend like that. When she says something that is on my taboo topics list (insulting and ridiculing others, the past (not reminiscing), my family, sex, her constant body and feelings report, etc) I tell her that I don't discuss those things and not to bring them up to me. Period. Then she does it every time, and then when I ask her not to she pulls something up from the past that is insulting, traumatizing, as if she's been just waiting for the chance to trigger me to want to sock her in the face, repeatedly.

I told her F off and blocked her number.

No one deserves that.

Not a friend. A piece of human garbage to purposely hurt someone else or invade their life. A piece of garbage, not even a human.

I'm sorry you're going through that. We all experience those people in our lives who suck.

Same here, and I echo what Jennifer said! You deserve far better than this in a friendship.

I agree with the others. You are not being mean, you are exercising self-care.

Thanks for the support everyone! I just realized that I've actually had more friends like this to the extent that they call me names. It's almost like I choose the wrong people to be my friends even though I'm good at making friends with my bright personality and kindness.

Self care ! Yes, remove her from you're life.

How were you treated when you were a child and when you were a teenager?

As a child I was treated like the weird one in school. The kid who was odd because I was so quiet but when I did talk it was always something really nice. This is alsp why i never made to many friends. I also had an extreme obsession with horses that its all I wanted to talk about most of the time and I was almost always out at the barn. I think people took advantage of me because I was always willing to be helpful, caring, and so incredibly nice. I would always do something for someone even if i wasn't comfortable with it. My dad left when I was 2 and my mom worked a lot so my grandparents took care of me. I was "grandma's little girl" so to speak.
As the teenager I am, I still have that niceness in my personality but I have become more unwilling to do certain things I was not comfortable in doing. I have extreme issues in expressing myself when I want. I also feel that no one really listens to me or takes me seriously. That everyone thinks I'm dumb or something because I always act silly in order to get people to laugh because it's how I sort of hide my depression. I love making people laugh.

The poster Divine1966 here shared a really helpful term: the unhealthy familiar. We are attracted to the familiar, to what we are used to. If the familiar is unhealthy, then we are attracted, drawn to something unhealthy.

So with you (I'm sorry that I did not realize that you are a teenager), I am wondering if you have had a lot of experience, both recently and in childhood, with people ignoring you, putting you down, and so that has become familiar to you--so familiar that it exerts a sort of perverse gravity on you and attracts you to more of it. How well does that resonate with your experience growing up and recently?

Often when people have difficulty expressing what they want it is because, in the past, especially in childhood, expressing what they wanted was viewed as a negative and they were criticized or punished for it. That is exactly what happened to me, and for many years, until i went to therapy, I had extreme difficulty asking for what I wanted. For example, I used to have trouble even asking people to pass me food at dinner. I usually couldn't manage it and I would take whatever was being passed around and never ask for anything that I myself wanted.

What do you think? How well does that line of thinking fit with your experience?

That exactly fits my experience. I was almost always ignored and put down and still often am, especially in elementary school and middle school. Sometimes even my own mother will ignore me if I talk about something I want or am interested in.
Also, I was often punished for asking for what I want. My mom often volunteers me for things I don't want to do, for example: taking my cousin back home when it is out of my way and his parents are just going to a store for one quick thing. I don't like this cousin one bit as he often thinks he can tell me what to do (I am the second oldest in grandchildren on my mom's side at 19, almost 20, and he is only 14). If I said no, she looks at me like I'm a bad person. She put me in this situation even when I was younger.
Come to think of it, when you mention the unhealthy familiar, whenever I find a friend who actually cares and listens to me when I talk about what I want to, it feels strange but good. The most person in my life that is like that is a friend from my old college (I am a transfer student) and is often busy but we talk when we can. Just to show how caring she is, she will go out of her way to call me late at night if I need someone to talk to. I don't force her to or anything like that, I'm not that type of person. Some nights, she comes back to her dorm at 5, goes to do errands and homework until about 10. If I tell her something bad that happened during my day, she will call as soon as she is done with everything.
I suppose she is the one who is making me want to change, striving for more friends like her. She made me realize that not all people are the same.

Perhaps it would help to look closely at your definition of friend. A friend is someone who listens to you, respects you, cares about your wellbeing. A person who bullies you, insists you do things you don't want to do, and other disrespectful behavior is not a friend.
