Have you talked to doctor about those? You may have to seek out psychologist and/or therapist to get answers you’re looking for.

I wish I could go back and get diagnosed sooner. I barely remember my 20’s due to major depressive episodes. But I’m happy I’m figuring it out now instead of 10 or 20 yrs from now!
