Why?

21 m here. Just me or does autism seem to get more intense/worse with age? For some reason it seemed as a kid I could just deal with it and be social with friends and play football etc. I stopped going to school when I was 13 and took me ages to get back to a “normal” level. I’m now 21 and just feel like any little thing I can’t cope with and it’s just making me constantly so annoyed to the point I actually cry but I’m not sad just tears. Is there a reason for this or is it a common thing? I’m not too clued up with it at all tbh as tbh I just most of the time refuse to acknowledge that I’m autistic as I’d rather just not have it and be normal. Sorry for the random yap it probs doesn’t make much sense as Im quite shit at English
