That is EXACTLY what depression does to you, takes away your hope, motivation, leaves you drained, tired, exhausted, etc. It takes away all your strength. Your suffering all of the signs and its "normal" what your going through, it sucks though yeah. All of us have felt that way one time or another, damn your sure as hell not alone.
And its a really vicious cycle as well, you don't want to do anything and then you get more depressed because your not doing anything ,etc. etc etc. I hope you can break out of it, won't be easy I know. Good luck man.
