I Want To Go Back To Who I Used To Be

*wants to cry and not stop*
Agoraphobia and depression and anxiety have thwarted me.
I'm 35 and I've been suffering with things for too long.
I'm an isolated loner. I don't have a life worthy of note.
I'm dragging my feet. The spark I used to have seems non existent.
I have a great partner but I am not happy.
I am upset and disgusted almost with myself and my life.

It seems impossible to think positively right now?
I'm seemingly stuck within four walls and hate myself so much.
