Crippling depression

I have been off porn for fifty three days. The last few weeks, I have been in the deepest darkest depression...nothing feels good, everything feels wrong. So numb....I believe this is probably regulating myself....but fuck...this is hard to want to live. No activities or hobbies make me happy....I suppose it will take time. I am 40. Been using since 13. I read a lot of people say everything was fine for them after a month or two... I think it's gonna take me a long longer. Has anyone else experienced this long depression?
