My son has autism, and I could of wrote this about him. He's 14, and has always struggled socially, he has such high anxiety about things, even the simplest of things, e.g hair cut etc.
Have you got access to cahms or anything like that? We are just starting that process, along with Youth Intervention. It's so hard, as you just need advice & support. Unfortunately there a lack of both in most areas.
Hope you manage to get the help you need x
