I also have a bossy sister. I'm the youngest of three children. My brother is 8 years older than me and my sister is 5 years older. If I tried to participate in a family conversation my siblings typically told me to be quite and that I didn't know what I was talking about. So, my self-esteem was low and I was pretty much silent during these conversations.

My sister and I grew closer as we got older and she went away to college, but she never has truly been the warm and fuzzy type. I'm very sensitive and emotional. We have spent a lot of time together over the years but when I had a manic episode I sent her some hurtful emails which of course I don't remember but she is still holding it against me and that was over 4 years ago.

She chose to form an even stronger friendship with my ex husband because of my actions which is really hurtful. I've thought about cutting all contact with her but my mom keeps saying she is your sister and when I'm gone who will you have left. I agree at some level with my mom, but it's not like we really have a relationship now. I would never tell her initimate secrets about my life or tell her about my therapy etc. for fear she would just turn around and tell my ex. I don't trust her at all and if I do have another episode I'm not sure if she would be there to support me anyway so for now we have this bs superficial relationship.

So that's where we are for now. She is very bossy, judgemental, etc.
