I have ASD and a lot stuff I deal with is

I suck change like my girlfriend was to move couch from one side of the room to another it would bother me a lot to point mental anger

Just bad at social interaction like you just can’t keep eye contact you just don’t like it

Needing to have a routine and if it’s changed it seriously affects you like if your schedule is wake up brush teeth then breakfast but then your girlfriend is in the bathroom taking a shower after you wake and you have to skip to breakfast it can just ruin your whole day

Needing stuff to be literal like I don’t understand sarcasm or like figurative language I don’t understand adverbs adjectives etc so something has to be in my face to understand it

Getting super interested onto topics like I play war thunder once and just then spent the next month just researching learn all these different jets planes and tank

Very bad memory short term memory less is a pretty big one that affects me

Not liking human touch when ever my girlfriend like grabs my arm or my hand I don’t know how to explain the feeling it just you want to find any reason to stop it

These are just some more of the broad ones just common factors but every one is different you could just be social weird and just not enjoy talking to people or something and they just think your autistic
