I don’t know what to do anymore and feel like I can’t do anything right

ATP I don’t know what to do anymore and feel like all the decisions I make or every small thing I do is an issue. Yesterday I went down a spiral of my Apple Pencil being switched with someone even though I clearly had the one that was mine since I have a specific tip on it. I also thought I hit a mailbox and someone’s car when I know I didn’t so I drove back around just to make sure I didn’t hit their car and then drove all the way back to the street the mailbox was on to make sure I didn’t hit that either. Today I dropped my phone screen down and the screen protector cracked. Tiny pieces of the screen protector came off in my hand when I picked it up but now I’m worried there’s tiny pieces left. It was outside the university science building door so now I’m paranoid someone’s going to step on them and hurt themselves. Idk what to do anymore. Should I contact someone from the school and let them know about the screen protector? I ended up driving an hour home so now I feel like it’s too late. I’m just over it.
