I’m just going to comment on work life - the truth is, the older I get the less I care about things like appearance. Depends on the profession of course but for f.e. office work - people don’t care. Especially not if it’s for medicall purpose (they could even have a problem with HR). I meam look at the older colleagues, they themselves look like shit, they don’t care.
But I remember my mid 20s and I was exactly the same, now I look back and it’s a bit funny. It’l be good, go for the braces :)
