Lucky enough to be self sufficient with time and money to spare. Still lost. Can you help me out with some insight or ideas?

My life was completely garbage until 25. I was naturally reserved as directly stated by my preschool. They asked my parents if they beat me at home. They didn't, but these parents of mine never considered I could be anything but normal. Which to someone like us is a completely absurd, enormous setback. I would really like to know how autistic people survived 200 years ago.

Sensory overload, failure to launch socially, fainting in crowds, unable to contribute in groups, inconsiderate & clueless parents, and so on 100% ensured my life would be almost as bad as it possibly gets. I'm sure you can imagine and some of you probably don't even have to since you lived the experience yourselves. 

Somehow managed to became an engineer. Somehow managed to steel my nerves and control myself enough to pass 1 interview. For a position 2 levels below entry level engineering position. Whatever, a job is a job. 

Of course the job was one where I had to work with and around 20 people. No peers. The job itself wasn't too challenging as I eventually got promoted to work an engineer, but the social aspect was driving me directly to exiting this life.

Driven up the wall I felt forced to start taking an interest in all things related to money. Budgeting, investing, markets, economy, and ways to not have to work. And then I started taking huge risks with my money. 

Long story short I got stupidly lucky. Now I don't have to work. There is money to spare, and a ton of time to do anything.

The problem is that I don't like much of anything. I feel chewed up by life and spat out. At 31 I would like to stay as far away from people as possible. I dislike travel because it seems impossible to handle sitting around 150 people and crying babies. I dislike trying new things and breaking my routines. There is nowhere I would like to go and nothing I would like to see. 

I've forced myself to do all the things I dislike. My life didn't improve and I did not start enjoying them. They're nothing but a source of constant anxiety and stress.

I don't know what to think about the way my life unfolded. I've tried confiding my only "friend" (he did a lot of harm and a lot of good in the past. I don't know what to think of him). He was somewhat supportive, but very ableist about where to go from here. He recommended practicing my social skills in bars among other bright ideas -_- Not sure he understands what autism is even after I described it to him.

What do I do from here? I went back to my childhood's special interest and I managed to take it really far. Then I burned out. I've exhausted a lot of solo entertainment and hobby options. I'm starting to feel like life has nothing further to offer.

Maybe some of you could share your experiences and point me in a direction? I am reaching out to psychologists as well and narrowed it down to 1. We're scheduling it, but I of course have to endure ridiculous amounts of anxiety stemming from it. Again. I thought I would never put myself in a position that would cause this much anxiety again, but here I am. ***. Autism is really lovely.
