Just want to know is this normal

I’ve been quit 7 weeks now and I am going through it mentally. I am prone to depression anyway and suffer from severe health anxiety that was under control for a while before I quit vape. This is the worst depression I have ever been in and no one prepared me for this. I feel like I’ve overcome the physical withdrawal and the habit but wow do I feel like rubbish. I don’t want to go anywhere, no joy in anything. Just a constant sadness that I want to shake so bad but can’t. How long does the body and mind go through withdrawal? I thought it was a month MAX but I still feel awful.
