Do I Have Autism? Need Advice

I feel the same I’m not diagnosed with autism but my brother is and I question if I have it, I tend to get overstimulated a lot and I don’t like a lot of food bc of all the flavors it’s too much for me I tend to mimic social cues or what other people are doing and I struggle with connecting emotionally I try but I just don’t understand

I've been wondering the same thing about myself! I am horrible in social situations and get uncomfortable making eye contact with people and overall I just feel different mentally than other people. You're not alone!!
