Depression sucks

I feel hopeless.  One thing after another I just feel like I am being kicked and every time I try to get back up I get kicked even harder. I am ready to lose everything and everyone so I can just run away. I am tired of the emotional abuse that my boyfriend places on me, I am tired of taking care of his mom dying of cancer. That is trying watching her suffer. I am tired of having a mother that still lives off of her 88 year old mom and refuses to get a job. I am tired of having to support my father because his ex wife took everything in the divorce and left him in a horrible position. And I am tired of being everyones shoulder and bank.  I hardly make ends meet, my job wont provide an upgrade or raise for 6 years now. I have applied for so many other jobs and nothing.  I am attending school to attain my bachelors degree to help with the job situation but now I am in serious debt with student loans because I don't qualify for assistance, but my income is considered low anywhere else. I am not making it. I have no one to rely on and no support. I am all alone in the world and just wish I could go to heaven already..... grrrr
