Im addicted to making myself sneeze, pulling out hair from this one part of my head (trichotillomiania, and yes, there's a bald patch the size of a quarter which I cover up by parting my hair and putting back my fringe) and biting my nails (been doin that for 10 years though). Should I really see a doctor? Should I tell anyone in my family?

Sneezing and pulling is recent. I LOOOVE sneezing... What do i do
