I didn't have the best childhood and it had a huge influence on me. But when I was around 15 I started to hate people touching me. It feels like someone is burning my skin and I want to punch them. Yesterday I nearly punched my teacher because he touched my shoulder for too long. I don't want this and people started to pick up on it. Why is this happening and what am I supposed to do? (Don't say therapy he doesn't help)
