My sleep schedule isn't totally great, but I have been noticing that my mood has been fluctuating fucking wildly from day to day.

Some days I'll wake up feeling great, and the whole day will go great.

Some other days I'll wake up feeling like shit, and that feeling will carry with me for the rest of the day. I won't accomplish anything that day, everything will be a fucking failure, and I feel defeated, tired, and wasted the whole day. I don't want to interact with anybody or talk to anybody. It's pretty pathetic.

Although I know sleep plays a huge role in this, but even when I do get relatively good sleep I still feel like shit the next day.

And the more I try to escape feeling like shit, the more shit I feel. It's terrible.

Advice?
