I don't know what your trauma or other possible issues are, but since you talked about the depression, I'll stick with that.

You say you are regressing. What worked for you before?

piggy momma has an excellent post.

This sort of question comes up repeatedly in the depression sub-forum, you could read old posts in there.

Please fight the isolation. Even if you have no friends or support network, some casual human contact is better than nothing. (And this is coming from someone with social anxiety.)



Maybe this will help....

When I was at rock bottom, I could not in any way straighten my mood out. Eventually, I decided to control what I could. For example, I went for a walk because it felt a tiny bit better for a few minutes and that was better than staring at the ceiling in abject misery. Pick some small, manageable things and gently get yourself to simply do them that day. I could not control my feelings, but unlike my resistant brain, my feet did what they were told.

I'm sorry you are going through this and hope things get better soon.
