Please help i'm 14 years old, and i want to die??? :(?

okay. i will try not to make this long because i know everyone hates reading long questions. anyways... basically i have had very severe anxiety and depression and some OCD for the past year. it has become so bad that i can hardly leave the house, i am now having to be homeschooled, and as a fourteen year old girl, its really hard for me not being able to see my friends. i remember way back when this had only been going on for a few months, my mom promised me i would be back in school and happy in no time... and now here i am with no improvement. i am seeing heaps on therapists and i am on an anti-depressant. I cry every night and to be honest i feel like my problems are tearing our family apart. my brother is saving money to move in with our grandparents because he's sick of hearing me cry every night. i feel like my life is going nowhere with improving. and quite frankly, i feel like i will have to live my life like this, and if i would have to live like this... i just feel like its not even worth it. i am not a very religious person.... but i was wondering if i should take up reading the bible and praying to god (i have tried this before) and maybe this will somehow miraculously give me a future? i don't know... because honestly i have just run out of ideas... and i basically just feel hopeless. :'( i want to die. i'm sick of cutting myself, and screaming and crying every night while i watch everyone else my age live comfort lives of normal teenagers. i have a lot to offer this world... and i can't live in a prison of something i can't control. please? if anyone has ANY advice, i would really appreciate it. thank you.
