I read your post on the PTSD forum. Chances are that your depression will relapse and you'll have to fight it all over again. I don't know how you started winning before but re-use those techniques that worked and work for this time around. Depression is one of the most prominent secondary diagnoses of PTSD. That's going to make this journey more difficult but know that it isn't impossible. There is a hope in this chaos.
I'm sorry that this happened to you and I'm sorry that you have to re-live that hell. I'll be thinking about you. PM if you just need someone to listen or just post on these forums, chances are that I'll come across them.
