I’m so tired

I don’t even know anymore...
I’m supposed to be starting therapy soon but I don’t know if that will even help..everything’s just blank, all the time. I don’t know what I want, when I want something, I can’t even make myself do the dishes most days. I don’t know what’s wrong with me and my brain.
I’ve been taking anti depressants for 6 years, switching medication when I feel like it’s not working anymore, and sometimes the medicine helped, and I would feel ok, I guess nothings working now.
And it’s not that I want to kill myself, either, so no one has to worry (not that any of you would care) but that’s really not it, it’s just blank in my mind; not even a black and white thought or picture screaming out to please bring the colour back— it’s just blank.
