This is pretty much my issue too. I have absolutely horrendous double standards.

"It's fine, no worries friend you can make a mistake, you're only human of course."

"I'm an absolute moron, a complete waste of oxygen, how could I possibly drop that pencil? If they weren't attached to me I'd drop my own damn hands! How could I be so absurd to think I deserve to find a partner when I can't even properly hold a pencil!?"

That kind of fun stuff lol
