Yeah, try to avoid it, I had a friend biting his nails very compulsively and eventually started to wear gloves lol.. in the he got rid of this bad habit, so try to replace your particular action or preventing by doing something else
I agree with Topcat, get some time off, travel and do different things, this is such a big decision that requires more time to ponder and consider very carefully.. good luck!
Sounds nice, a bit expansive though, Ive been seeing a lot of ads lately from Invisalign, well, keep us updated I may consider it in the future if its really worth it :D
When I feel down I try to think about successful bald people.. like Jeff Bezos from Amazon! my baldness doesnt define my entire identity, im much more than that! hope it can help!
