Potential Autism Insecurity

My psychiatrist told me I might have autism a while ago and recommended I get tested for it, but I was scared and denied it. After a while, I spoke to a few of my close friends about it. I’ve had a lot of communication issues and I suck at social cues, I’m sensitive both to bright light and loud noise and I make weird noises I can’t control when I’m stressed. I’ve shown many other symptoms of autism but for some reason I don’t want to get tested because I feel insecure. I know having autism is nothing bad I’m just…I can’t handle it.
