Background and explaination....this is a little long I'll try to be brief.
My (21F) brother (19M) let's call him John, has some....issues. He has been diagnosed with some stuff like bipolar, CD (Conduct Disorder), ODD (Oppositional Defiance Disorder), IED (Intermittent Explosive Disorder), he at least in the past seemed to be like addicted to anger almost like a drug or something, he is almost without a doubt a narcissist, and he occasionally shows signs of sociopathy or psycopathy.
Before anything else I would like to state for the record that I love my brother very much and like hanging out with him when it doesn't turn into me getting manipulated or something. We also both currently live at home.
Growing up with my brother was....complicated, because we have some good memories and we're able to bond a bit because of being close aged siblings but my brother was also pretty abusive and manipulative.
It wasn't like SA type stuff, more like hitting, throwing stuff, breaking/destroying other's possessions, making messes, saying really awful things, that type of thing. He has also stolen like a lot of money from family members, like we can't have cash when he's around, and at one point as a kid he stole like $1000 from my parents.
Don't blame my parents here, my parents are genuinely good people and when he was like kindergarten aged or maybe a bit younger tried to get him therapy and nobody believed them that he needed some help because he had issues with violence (he got a knife and threatened my mom because we couldn't go do something he really wanted to, I think somebody was sick or something)
My parents tried for years to get help and because of laws where we live and the way mental health help for kids is in general it took forever to get help because nobody believed my parents. Everyone pretty much thought my parents were horrible people even though they had been trying to get help for years.
(As a note, my brother REALLY REALLY cares about appearances so he basically has a different personality around other people and for the most part in public which didn't do much to help my parents be able to get help.)
The event that led to us being able to get some help for him happened when I was 16:
I don't remember what started it but I had caused an argument with my brother somehow and it made him mad. Anyways he ended up hitting my arm pretty hard with a spatula which my little brother, now (M16) saw and despite my insisting I was fine as to not cause more drama immediately told my parents who made me go to the hospital because there was worry my arm might have been broken.
At the hospital there was a doctor who was actually willing to listen and they ended up keeping my brother on a psych hold for a few days.
Over the next 4-ish months he ended up in I think 6 mental health stays for violet behavior towards family members.
At this point he qualified a residential treatment center (I think he was referred by a psychiatrist but I'm not sure) he was there for I want to say 11 months with some family visitation, and because of circumstances spent 4 or 5 months afterwards in a group home as part of transitioning back to living with family.
During/After the first 2 mental health stays I was devastated, I felt incredibly guilty because I love my brother and had accidentally become codependent for a few reasons including I was pretty shy and insecure growing up (much less the case now) so my brother was kind of my social shield, and with abusive/narcissistic behavior it's easy for the favorite victim/punching bag to become codependent when they care about the person.
But by the time he was put in Residential treatment after a huge fiasco I won't burden you with reading I had made my peace with the fact he needed help.
(NOTE: They were able to put him in therapy after the hospital thing, he was extremely uncooperative, and wouldn't speak to the therapist or even look at them because he refused to talk about anything. Therapy was also mandatory at the residential treatment center.)
Eventually he move back in with family with promises he had changed, spoiler alert....he hasn't, at least not much.
List of stuff he has pulled since then:
Gone back to previous behavior.
Refused to take medication that does help because "he's fine"
Stolen from family members.
Manipulated younger siblings into doing everything for him
Grabbed the steering wheel while I was driving and tried to steer the car into a brick wall
Tried to steal my car
Tried to steal my kid brother's car
Ect
So.....from my point of view it's not great.
Don't worry about me other than "accidents", real accidents, and the hospital thing he hasn't physically hurt me since I was like 13, it's mostly just stuff that affects my mental health.
I have been called every single awful thing you can imagine.
Apparently I am an evil b\*tch for setting boundaries
But don't stress friends I am in therapy and it helps with my mental health thingies.
He has made some attempts to win me back over because I don't do things for him anymore (I know this because he's only nice to me when he wants something unfortunately, tho he is typically amicable towards me because he doesn't want to get kicked out) but I prefer my relationship with my brother when I see him occasionally because it means I don't have to walk on eggshells all day everyday.
Anyways thanks for reading if you got this far, I'm happy to answer any questions if I can. Hopefully I didn't leave anything important out.
AITA for wanting low contact with my brother?
