If potentially having mental illness is bothering you, see a doctor about it.
I got diagnosed in my 30s and holy damn meds changed everything. I took adhd meds for first time and 45 mins later remember thinking ‘is this how normies are all the time? You can think something and just do it?? No prep, no build up?!’
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!
