Well, Ive never had acne, but my confidence can be pretty low at times. I'm sometimes a bit of a recluse because I don't like dealing with new people. Ill tell you the worst thing with new people, I cant hear them!
It takes me a wee while to train myself to people's voices because its new and unfamiliar, and new people who dont know can give me some amount of shit sometimes. Seriously man, you dont know how lucky you are!
Low confidence happens to everyone, and we do all get those negative thoughts, but to be honest, we still have to get up the next day and immerse ourselves in our lives....just remember, when you see someone who is loud, super confident, outgoing etc. they may in fact just be putting on a massive front to hide their own fear.
Anyway, p&b is not a good place to talk about such stuff, you'll get ripped to shreds!
