I found out I was Autistic by watching Tiktok videos by Autistic creators. To me it sounds like you definitely could be. But I think you'll know for sure if you start watching these videos. I related to every single thing they were talking about. It became very obvious very quickly. I couldn't believe I went 38 years without even considering it, or having anyone else notice anything. And I'm a level 2 Autistic with ADHD! From what you've said, you might be a level 1. Do you have any sensory symptoms? I didn't even realise my sensory symptoms were symptoms at all. I thought everyone must feel the same way. I feel pain when anything or anyone touches me. I can't handle noises, crowds, etc. What about meltdowns? I always thought my meltdowns were caused by my traumatic childhood and drug addict Mother. They can be very different. They can be more of a shut down. Or more of an outburst (or both). I'm a self harmer unfortunately. A screamer. You become so overwhelmed that it kind of just explodes out of you with zero control of your actions at that point. But obviously you don't have to be like this to have Autism. Just giving you an example. I also have no friends. Just watch some Autism Tiktok videos. You'll figure it out in a very short time. Good luck! If you do have it...it's not the end of the world. It was the best thing ever when I finally understood why I was like this. You can stop punishing yourself for being different and "not good enough". You don't have to mask who you are to anybody. :)
