I'm so scared of moths!?

I know it sounds silly but I'm completely terrified of moths. On the scary scale of 1 being I don't mind them and 10 being I hate them I probably 20. If there's a small one in a room, I can't go in. If I see one I freeze and can't move. It's really embarrassing and my brother keeps taking the mick. It's really hard at the moment 'cause there are lots of moths about. I really want to be less scared of them but I don't know how. Please help me. By the way, I think I got my fear when I woke up one night and there was a massive moths on my bedroom wall about a meter from my head.
