PLEASE HELP

Hello,
I used nair on my upper lip and the skin is terribly irritated/inflamed/etc. My family said
that it wasn't noticable, but I get really self-conscious (i used to have social
anxiety/body dysmorphic disorder) and couldn't bring myself to go to school today.
Could someone PLEASE give me advice on how to get this irritation to go away
(creams, treatments, etc). My mom made an appointment with the derm but I might
end up avoiding it... I really want to get rid of the redness/scabs, because it's just
another excuse not to go outside. I have recently been treated for social phobia....
and I don't want a relapse...
