I'm afraid to go out because of the pimple on my forehead.

This morning, I couldn't believe my eyes the moment I looked in the mirror. A large, red pimple has taken hold right in the middle of my forehead, weighing heavily on my mind all day. I started my day on edge, wondering if I ate something wrong yesterday, or if it was a recent makeup change. Whenever something like this popped up, I dreaded going out, and I couldn't even raise my head because it felt like everyone was staring at my forehead. Come to think of it, my skin seemed to be getting flaky due to the changing seasons, so perhaps I'd neglected my exfoliation? I carefully tracked my skin and saw that it had started to get a bit rough last week. I guess I should have taken more precautions then. Usually, when I track my skin, I see patterns, but this time, I guess I was a little sluggish. Honestly, my skin is so sensitive that I feel like I'd be toxic if I just pushed it away, but if I just left it alone, the white patches around the pimple would be unsightly. When I get these kinds of pimples, I can't figure out whether I should gently exfoliate after washing my face, or just apply some ointment and wait it out. How do you deal with your skin suddenly becoming sensitive like mine? Even at this age, I feel so small when it comes to skin problems. I feel like I want to hide right away.
