Do most people have some level of mental health problems?

I've came to terms with the fact that I'm autistic, or at the very least suffer from sensory issues and I'm extremely socially inept. I've flunked out of my master's because of it and I'm embarrassed at what a recluse I was then. I didn't talk to anyone. I don't know why I did that. I chronically avoid groups of people because I suffer from shutdowns where I become mute. I'm hoping the SSRIs will help. But alot of my classmates displayed some quirk. I bet they actually put in the effort to address it, unlike me. And I was just thinking back to my kid years. I'm 25 soon. One person has hyperactivity disorder, maybe someone else had something else, it wasn't uncommon to have some sort of problem (early balding, asthma). Though most kids were largely normal, and the odder ones I suppose struggled more to make friends.
