I know exactly how you feel. I'd cry every single night before i went on Accutane...
But in reality - it's not that important to other as you think it is. Many of my friends have acne and I NEVER SEE ANY. Never. When i think of their faces, i can't even remember how acne would look like on them.. It's like it's not there. And i might subconsciously look at their acne sometimes when we talk but it's like a quick glance it doesn't mean anything and you think about it when you do it. it's like a glance at their hair or nose.. It's nothing. But you might be questioning yourself oh god, did they notice, do they hate me, are they disgusted? It's not like that.
And i've learnt one quite interesting thing while experiencing the both perspectives. When i had acne the easiest way was just look down and pretend i wasn't there and avoid all the eye contact avoid seeing their eyes traveling all over my face...But i didn't know back then, people notice it. People see and feel you're avoiding, they feel how bad you feel, they feel your insecurities. It makes them uncomfortable and awkward because they don't know what to do. And some might use the fact you don't appreciate yourself for bringing you down or using you. When you don't love yourself, others won't either because they see they can "afford you! "
if you show confidence, acne won't matter. I've seen a lovely sight of numerous guys with acne, i didn't care i think acne made them sooooooo much more attractive just because i thought to myself: oh god he is so brave and so comfortable in his own skin he can do it all blah blah But it's the truth, my truth at least.
