Some days, even multiple times a day, I feel a sudden wave of guilt and embarrassment like I've done something wrong and people are mad at me and I should be ashamed, but there's no concrete logical explanation for the feeling. I'm surfing the internet going through a bunch of different fleeting thoughts of no real importance, and then I get struck with it, like a baseball bat of guilt that keeps hitting me on the back of the head by an angry teacher. I'm always paranoid that I've made a big social mistake that people won't forgive me for. I have to rack my brain hard to draw up any thoughts that may have caused this feeling.
