Depression has Set In

I have being fighting depression ever since I was hurt on the job nearly 3 years ago. One of the only things that my life joy was my family. Connor my little man helped alot. Well since I had to leave due to circumstances and I do not know if and when I will get back to them. I am slow slipping down. The more I think about them the more it hurts. I need them in my life. Please help!!!!!!!!!
