I want to know if someone has also experienced this. 

For the past few months I’ve been going through a weird situation. 

Pretty much I get anxious over nothing, and I think my brain thinks I need SOMETHING to be anxious over, so it brings back something bad I did YEARS ago and I feel horrible. Just recently I had this, and I was thinking about a MIDDLE SCHOOL RELATIONSHIP. During these times I feel like a criminal, the worst person ever. I don’t deserve anything. It’s usually things I’ve forgotten about, so I know the things I did aren’t as serious as I make it out to be in that moment.

Does anyone experience this? Any advice?
