WHY?

I feel like I'm sinking into a dark hole it's becoming more and more confusing. I feel like I've been torn into a million pieces just for people to walk all over. I feel as if I can't handle life, It's just too much for me. How depressing it is to think you can't keep up with everything going on around you! Makes me wonder if I'll be strong enough to make it through the rest of my life...I think my problem is that I'm trying to do it all by myself. My anxiety and chest pains are really getting to me these past couple weeks. :( I'm so sick of it!! WHY is all of this happening?? :(  UGHHH!!
