How did you get past the “wow, I hate where I am in life” moment and then start taking action question from a discouraged 27yr old

I don't like where I am in life. I despise it actually, but then thinking about that puts me in a mindset of self pity and my brain is all bogged down and I can't think straight because of how discouraged I am.

How did you swim thru the negative self loathing in your mind and find the part of you that needed that encouraging push?

What uplifting affirmation really propelled you forward?

I am already pessimistic enough. I need some good ole over the top optimism.
