I'm 15, and I'm starting to get worried and didn't want to ask or tell no one in case they think I'm crazy but ever since 2-3 years ago I was watching TV and couldn't turn down/ up the volume unless it was left on an even number and now it's like I have to do everything I tell my self in my head, like if I'm walking up the stairs and I say to my self in my head 'if you don't go down stairs and back up 5 times you'll get bad luck' I have to do it other wise I truly believe It will happen and sometimes it's really bad and I just want to know is this normal ?? Will it stop ???
