I don't know if you are feeling a kind of stuck-ness or anxiety about the unwanted upper lip hair. I wonder if you are speaking out loud a lot of fears people have but are to afraid to mention. Through your post/evidence I noticed that even though you are feeling stuck/anxious/scared that you ended with wanting to figure out how to shave that hair.

I might not be able to provide answers but I definitely empathise with this struggle. I dealt with my through hair removal cream :P
