Can't get through alone :(

Hi everyone,

I have been extremely depressed for months now, in addition to suffering from PTSD. It's at the point now where I feel a constant burning pain in my chest... I'm just so hurt all the time, even when I'm not thinking of things that upset me :( My work performance has seriously suffered since most days I can't even find the strength to get out of bed :( I'm getting help from both a therapist and psychiatrist, but it still isn't enough :(

The worst part of all of this is that I'm all alone :( My family has turned their backs on me, and I have no one else. How do I get through this pain alone? I'm really starting to feel like this pain isn't worth being alive :( How do I pull myself out of this on my own? No one cares :(
