I also was extremely depressed to the point where I refused to get out of bed or take a shower or even brush my teeth. My husband had to dress me and wash me although I wasn't physically disabled. I just didn't care. All I wanted back then is to die.
My PCP prescribed celexa - it took me about 3 weeks to get to the no-depression at all stage. It was such a relief for all of my family. Although after my setback I'm starting to feel this familiar depression signs again
Good luck to you! I hope you'll find the right cure for your condition!
