[Acne] A doctor made a really hurtful comment about my face's appearance - how can I get past this and be confident in my skin?

Beauty Tips For Body Care
I was put on a med a couple weeks ago for mental health reasons, but it ended up causing a rash (that could've become fatal) so I had to stop. My left leg and butt were covered in hives. Because of the severity of the side effect, I went to urgent care. After waiting over an hour the doctor finally comes in and without reading my file straight up assumes the rash is on my face...when it was just my typical acne/appearance. It was very upsetting to have that assumption made, when I've been struggling with acne for over ten years (I'm 23 now).My question is how do /you/ maintain confidence less-than-perfect skin?
