I have questions about my aunt may trigger

My aunt is 56 years old and has bipolor. Mental illness is common in her siblings my mom has scitzophrenia t my uncle major depression my other uncle thought he was God.
Any way My aunt has these days. I know with bipolor you have ups and downs and stuff. However this is what i am wondering.
My aunt can be so mean to me. A couple of examples are when she stopped taking her meds she began to stab her teddy bears with a knife and I told her son she was very ill and she could put on a front for him when he called that seemed ok. To get me back she emailed every person in my family and told them I broke in her house ate all her cookies threw her phone in the ditch opened her courtains moved her dog food (she has no dog) and every one stopped talking to me for a year. The she apologized and told every one she was ill when she said that. More recently she has gone behind my back after i spent hours helping her do stuff and told every one that I made fun of her illness and how insinsative I was??? Not true again. I used to call her and check on her twice a week as her son lives far away and is unable to. She is so mean to me. She told me yesterday that my therapists actually hate me and they can not care about any one they work with as it is their job to pretend and that I need to stop building my foundation of healing based on what they say and do for me as they help me. SHe said they probably hate me and that I am to nice and to loving and that makes people sick.
She has called me a bit**. She also has called me suicidal blamed me and hung up on me and all the other family members rushed to her house after i called them and one of them said if she dies its your fault.
I have done nothing to her. When I was 9 i was placed with her after my mom went to prison. One day Ii said I want to go live with this person so she packed my stuff and dropped me off at her house.?????
I do not call her very often anymore. i dont check on her I told someone else in my family that i can not be that person.
Sometimes she is sooooo nice she tells me she loves me and I am the sweetest person she knows and she is sorry.
Is this bipolor???? Or is it just meanness? If its bipolor I can probably just let it go easier but if not I cant do it anymore. I was so triggered last night I cried for about 4 hours about what she said about my Therapists because it scared me????

i'm sooo sorry you have had these interactions with your aunt. i know it must hurt and is also baffling. can't give you a dx on her but there's one piece of good advice my T told me i'd like to pass on to you for your protection:
he asked, how do you stay healthy in an unhealthy relationship?
his answer: A HEALTHY DISTANCE...(i didn't have a clue at the time...)
and it sounds like you are trying to do just that.
as for your relationship with your T..to reassure you...i'm certain it's working just like it is supposed to be. your T is there for you so don't second guess yourself and your worth. you are of value and worth.

I also can't really give you a diagnosis, but I'll say a couple things. If you're a mean person, you probably don't stab teddy bears just cause you're mean, right? And she does a lot of these things when she goes off of her meds as you said also, that's also an indication that she's not like that all the time. It may be bipolar, or something akin to it. The point is, and I think what you're looking for, is that your aunt doesn't hate you, based on what you are saying. It just sounds like she isn't well and needs some help. But you need to do what is right for you, and if keeping distance is what's right for you, then that's what you need to do.

She is already dx with bipolar. I was just wondering if the meanness was part of being bipolar.
I have dealt with people alot meaner then her its just that her attacks are unpredictiable. She loves me hates me.

A lot of us bipolars run hot&cold when it comes to meanness&being loving. It can be a part of a manic episode-mania doesn't always manifest as delusions of grandeur, shopping sprees, or hyperactivity. We may manifest mania as irritability, meanness, cruelty,etc.
Remember she is sick, but you DON'T have to put up with her crap! She sounds like my mother-nice one minute, nasty the next with a lot of backstabbing&destruction of my personal property. I just don't put up with her anymore. Your Aunt is family, but there are reasonable limits&you're not being mean if you put your foot down&say I'm not playing your game anymore.
Like myself, you seem to need to not take an obviously mentally ill person's cruelty/lies personally. I have a real hard time not taking things personally&I'm even worse if there's criticism. It's to the point where I am hurt so badly inside that I can't tell if ANY of what they're saying has truth to it.
hang in there-I'd say stay away from her until she starts acting nice-I know it's confusing&unpredictable, but sometimes nice is better than NEVER nice.
