<human>: Can you condense the text into a few key points?

they are borderline retard, if i wasn't there to help them they would be homeless asking for tips to buy some food or in mental hospital,

they relay on me too much because i'm the only son in the familly so they expect that my duty is to fucking assist them in everythings but only when they need it, i have 2 sisters but you know, girls are useless, they are more preoccupied to know if "brandon" or "joshua" have a crush on them or what their friends do on facebook

they fucking make me mad, they give me the impression that i'm the parent of my parents and sisters

they are incapable to sort their own problems, incapable of taking the right decisions, incapable of being successful at any things.

i sometimes ask them " if i weren't here what would you do ?" they don't know what to say

my health is completly fucked up beyond "repair" (i'm 25 years old), a combination of incredibly shitty genetics, luck, family and environment and some mistakes,
 i'm tired of trying to manage all of this, it's too much for me, i'm becoming literaly insane and i feel i have the brain of a 90 years old man

what should i do?
<bot>: my Family are like childrens incapable of taking care of themselves or solves their own problems and they count on me and i'm fed up/ what should i do reddit?
