New to the Crew: My ASD Diagnosis Story

heyyy. I'm new to the crew, was diagnosed when I was 2. I got reeeaaally sick after my 2 year shots, like I thought I was gonna d!e. and I was walking, talking and out of diapers at that point. after I got over my sickness, I regressed. I couldn't walk, wouldn't talk, and was back in diapers until my parents finally took me to a doctor to see what was wrong with me. A few visits later I was diagnosed with ASD. Its not severe, just barely on the spectrum, but it still counts right? I show multiple signs such as hypersensitivity to sounds and smells, avoiding eye contact, and inability to read social cues. can somebody give me some advice on how to cope and maybe some tips to avoid future meltdowns?
