Trying to Understand Myself: Could I Have Autism?

New here. Already made one post on my past psychosis however I'm also here to try understand myself more. I've been toying back and forth with the idea that j might have autism but I really don't know for sure. I'm a trans man, my mum is autistic, my uncle is and grandad was from her side of the family also. Also the fact that I've had psychosis along side all this makes me feel like it may be more likely. I don't know what it is. My girlfriend jokes that I have it alot. I do get fixated on things, get over excited and feel the need to jump or wiggle my legs at the mention of my current favourite interest the game Splatoon lol. I can find myself acting more childlike sometimes and zoning out. I like to fiddle with things with nice textures but I feel like that's not enough to make my autistic yet at the same time they could be signs of some autism there. I have alot of autistic friends some say I might have it, please excuse me as I don't know loads about autism only what I've learned from friends and family. I'd appreciate opinions and more insight. Thank you.
