You might want to try Ketamine. In some countries it's now available legally from neurologists as nose spray. If not, get it from the dark net or a friend in the rave community. Or ask as friend who is a veterinarian. You get mix your own nose spray with that.
Before Ketamine, I never in my life had been able to get into a group of people with them being closer than about 50cm to me. Which means: I could never join a dancefloor.
With Ketamine, that poof went away, and I could.
The same happened for a couple of my neurodiverse friends. One girl her hole life could not be in the same room as others while eating. Now she can.
A single dose also has anti-depressant effects for five days.
Interestingly, it's now in some countries allowed to be used as treatment for social anxiety after positives studies on that. On the other hand, there is now a clinical study that say it's not better than a placebo. Weird.
However, for me (and my nerd friends) the before/after effect is so drastic, I can rule out a placebo effect. My neurologist agrees. I trust clinical studies and always consult them, but something must have gone wrong there.
And yes, this is a good example of a substance that in many countries can get you into jail, while in other countries it can make a most DRAMATIC positive change in your life.
