I purchased the BREATHE key for myself a year ago; it was a way for me to attempt to get my anxiety under control. I wore it everyday, and it became somewhat of a security blanket for me. This year, a very good friend of mine was studying to take her MCAT. She was insanely nervous and her anxiety hit crazy levels. Since she lives in upstate New York and I live in central New Jersey, it was hard for me because I couldn't physically be there for her. We met up for GeekyCon in Orlando in July this year (we actually met at LeakyCon last year) and I was FINALLY able to give her my key. She's been doing better, and she passed her MCAT with flying colors.
