Burned out?

As neurodivergent I was bullied a big part of my life. People were annoyed that I'm slow, social awkward, etc. I healed many years ago, I became calmer, I accepted myself, I forgot about that feeling. Recently suddenly I became self-criticizing and self-blaming for no reason. Logically I understand that nothing is wrong in making mistakes but one part of me is being sensitive to any small mistakes and misunderstanding. I was thinking about what happened suddenly. I found that recently I'm trying to study, working, handling family things a lot without much possibility to relax. I thought about making less pressure on myself but I feel like if I stop improving myself, I will be miserable very soon. Maybe I should to find way to make myself happy with any small things? Anybody had similar experience?
