Am I ever gonna get over the self hatred?

I'm trying to detect the triggers...
Is it physical exhaustion and blaming myself for causing it?
Constant disappointment in myself?
Mistakes (that turned out to be okay in reality...) but still grave if turned out otherwise?
Disappointing some people I look up to and respect?
Failing to take care of myself properly?
Failing to manage stress from work and other events?
Failing to focus and keeping the procrastination?

I usually like to radiate good energy around people, but now my closest ones are noticing how sad have I been looking recently.

Is it... the smooth transition of the cycle?

I wish I could find a solution to this low mood of mine.
