In gaming we call this "git gud". You obviously need more practice because you haven't moved on from a specific failure. Learn from it then beat it next time. Owning failure is part of how you accelerate learning.

This is an odd reason to not donate. Not that I'm donating either... but I've already donated to plenty other organisations this year.
