how do i know if i have audhd or just adhd?

I definitely feel like i also have autism along with my adhd. I’m extremely sensitive to feelings and sounds and can be extremely picky with my food and things like that. I know it’s not much of a reason but compared to my adhd peers i feel as though my symptoms are a bit different. I panic and feel EXTREMELY uncomfortable and angry when it’s too hot, if i’m wearing something i don’t like the feeling of or if i hear something i dislike. i’m aware that this occurs in adhd too but i feel like the way i react to it and feel it makes me wonder if it’s just adhd? i don’t think this was a very good explanation but im a bit anxious lol.. but please give me ur thoughts!!
