Supposed to spend new year eve with a man but..

Hey,I was supposed to spend 4 days around the 1st with someone I really like. I already met him twice, once with other people and once with just him an I. It was awesome.I'm suffering from acne for 7 years. I'm 20 now. And this week, it's really bad. Big white spots. Disgusting. So I think I'm not gonna see him. I'm way too ugly and very much uncomfortable with myself.Normaly, I already have a huge lack of self-confidence. But with this. I just can't do it.So I'm gonna tell him tonight. We were supposed to travel and meet at Paris the 29th.
