Do you hold any grudge against yourself or someone else?

Merriam Webster Definition:
Grudge: to give, do, or allow (something) in a reluctant or unwilling way: to dislike or feel angry toward (someone) for something.

I tend to internalize and beat myself up for things I've done that are wrong or mistakes I have made, or in areas where I failed at something. I was trying really hard to do well, but sometimes I carry the guilt, shame, and disappointment around with me like a school girl with a loaded down backpack.
