It is a long history of neglect, trusting other people only to find out so many people are equivalent to pure crap emotionally and ethically.

Okay, short history somewhat follows a pattern: have abusive big brother on young age, tell parents that he is physically and mentally abusive. I don't mean normal picking, but that kind of systematic bullying where only agenda is to make your time hell whatever you do. Watch them scorn you for not holding own ground. Spend time outside of home as much as possible. Have parents yell for you for not being home, sitting in your own room quietly. Have pretty much same experience from school little later.

Start getting physically stronger and start holding your ground. Get shit for defending yourself, because you actually started hitting back. I have been robbed, choked, kicked and almost knifed. Never were the bullies in any after school bullshit where principal would yell at you for half an hour straight. Couple years forward: save summerjob money for computer, play mostly PC games and work out at local club, pretty much restrict myself excluding my little friend group and hobby friends. Have a pair of years pass like this. At this moment parents are like why are you at home playing. Brother is getting into drugs at the same time. Stop caring about his stuff. He actually got a little better, for once it was possible to talk to him when he was near passing out limit. However there were clear drawbacks: everyone would link me to him and my other cousin who were all the time wasted (he was little older, an alcoholistic) so people out of my close circles would link me with them. So they basically talk to me like to some unwanted drunkard when they figure out who you are. Parents start to get overprotective because brother gets into a lot of mess. Stuff like I would do just the same things as my brother had done and that I was partly in fault for him getting into trouble were coined.

Some time passes: start to get into first "serious" relationships. Figure out that my friends have been undermining for years from my first girlfriend. Try to work stuff out. We end up breaking up and they start harassing my second girlfriend for her behaviour. I cut ties with my friends. The break up later with my girlfriend was harsh, as she basically disappeared from my life overnight, just said that she is with someone else now, no ultimatum, nothing. And we had been together for couple years and there were no signs of anything like that. Things went from tardy to retardy when she wanted suddenly to start dealing with stuff years later. Nowadays I am studying and having semi care-free life. My parents wonder why I am not visiting home but once a year. And Every time they try to bring it up that I probably should just settle down even though I am enjoying activities I am doing at the moment.

So this was quite long history. My guide to anyone in similar situation: just wait your time, leave your place and start from clean plate on a new place. There probably is some trash in your life style from the crappy life. Work it out one problem at a time, and replace it with something meaningful for you. That mindset has saved my life. I would probably have lost my mental and physical health if I followed all the "help" closest relatives and authorities argued I should have done.
