It seems like there is a lot of good advice for you and lots of evidence you are not alone. I suffered from depression in the past as well but I don't believe mine was chemical but then maybe learning new ways to deal with stuff can change your brain chemistry (I believe it can). I do recommend talk therapy with your medication. That is what I did. Switch therapists til you find the right one. I didn't realize how much of a difference that mattered. I have seen about 6 different therapists until the right one and the difference was obvious the first day.

It took years to get thru but now I am never clinically depressed - ever! (I'm sure situations will arise that are difficult but hopefully I have the right tools to deal with tough times). Remember take baby steps and yes if you get out of bed it is an accomplishment to celebrate, and don't beat yourself up when you have a rough time.
