When I was 10 I developed this weird habbit were I would take deep breaths after every 15 seconds or so but later sometime in year 7 to 8 I had forgot about it but in Year 9 I remembered I had it and know it's back and it's incredibly fustrating. I recently got a ear infection and all I could think about was my ears and didn't focus on my breathing so I forgotten about. Know after I've taken my anti-biotics and gotten over it this deep breathing habbit is now back.

What is wrong?
