I need to move out. I can't cope with living here. Everyone blames me for everything and no one really loves me. My siblings are nasty to me and my parents don't really want anything to do with me. I just want to live somwhere else but I don't have anywhere to go. I have no money and none of my other family want anything to do with me 
I could have written exactly this when I first started to suffer from bipolar disorder, I had convinced myself that the only way to escape my problems was to escape my family because I felt that they didn't love me because they were always on my case or nagging, soon enough I moved out and din't look back but it didn't solve my problems, I was lonely, depressed and suffering from extreme mood swings. It took a long time for me to realise that my family wern't the problem and the reason they were on my case is because they were worried about me and could see first hand how I was acting was down to my condition not me but I refused to admit it or see it.
try to see that your family love you and are probably only worried about you, thw whole sibbling rivalry is probably down to them thinking you are acting strangely and not like you but that is because of your condition, are you getting any support or treatment at the moment
keep posting, we have all been there at one point or another
