Getting Tested for Autism as an Adult

I was diagnosed with very slight autism not too long ago, and I'm only 20. I think that I took some sort of test, but I can't remember. But here are my signs of autism: difficulty learning, difficulty concentrating, sensitive to loud noises & some bright lights, not being able to lie is one of the strange symptoms that I've looked up. Not being able to sit still for a long time, fixated on one activity/thing. This is a come and go problem for me. It's not always constant. Difficulty understanding ones feelings, not being able to read a person's expressions. Getting anxious when it comes to socializing. Difficulty making friends (this is a huge issue for me), accidentally letting your mouth speak before you think. Unable to understand sarcasm, even when it's playful.

I'm currently in the process of getting a neuro psych eval to see if I have autism. I've only gone to 1 out of the 4 appointments tho. The first one was sorta like a therapy intake session where I just told them about all my habits, symptoms, and just over all about myself. Next 2 sessions are the actual testing session then I will get my results on the last session

Me too ;-;
