Dont take advice from anyone unless youve asked for it. You will have uncontrollable acne for the next ten years so try not to put your life on hold. Exercise will make your acne worse, but its not worth getting unfit just to look slightly better. Diet wont make a difference to your acne, so dont bother trying to cut out dairy/ sugar/ gluten, although you should watch what you eat as you put on weight pretty easily and the older you get the less easy it is to lose it. Over the counter treatments wont work so save your money and go see a dermatologist. Get a girlfriend even though you don't really want one, as its good practice for when you do. Tryto improve your social skills by getting a weekend job or joining a club (dont get a paper round, because waking up at 5am isnt really character building, people just say it is to make themselves feel better). Its not all in your head, even though a lot of people will tell you that it is, but just because you hate yourself it doesnt mean that everyone else will. People dont really understand what they are saying, theyre just repeating phrases that theyve heard before because their ego wont allow them to admit they have nothing useful to say. Dont admit your feelings to anyone else, unless you trust them 100%, because they will use your weakness against you when it suits them. Dont talk to your parents about it because they'll just make you feel worse.
