Don't self diagnose, really please just get a proper assessment by a good neuropsychologist. I had a suspicion that I had ASD, and I found out I had ADHD instead which surprised me. And part of ADHD is ignoring social cues subconsciously. If you end up having ADHD, OCD and anxiety for example, there are medications for that can change your life.
Even if the diagnosis ends up being some sort of ASD, ASD is a diverse condition with many subparts, so understanding how the machine of you works will be helpful. You also get an IQ test so you know what kind of gifted you are and there are books and therapy programs that can help you manage all of the diagnoses. Instead of giving up on the world and going full NEET, understand yourself first.
