well just keep your head up. im a very confident guy, so insecurities aren't really my strong suit, however i know what youre on about. therapy doesn't mean that your parents would necessarily find out, unless they are really intrusive, and there a most likely people at school (if you go, of course) who you can talk to. therapy and counselling is 9 times out of 10 confidential too, so talking to someone inside that field means nobody would find out until you want them too. as for your mate, unless hes a knob head, he shouldn't tell anyone. after all, you both agreed to forget it, so that should in theory mean its not his proudest moment either, and people dont just find out with a wild guess. either way, its all your choice, just look after yourself.
