I just went back to read through your old posts. Lovbyts did everything he could to steer you in the right direction before you started. You told him to leave the thread as you did not like what he was saying. He was not the only one telling you not to do this, but he is the one that really tried to pound the issue of ED with you. I really hate posts like this because we need to find a way to get through to people your age who we want to help but for some reason we cant.
I hope it all works out, and you should realize that sometimes old shits like some of us might know something that is worth listening to.
You are not alone and I made the same mistake you did at your age. But, the internet did not even exist then and finding this information was a heck of a lot harder. All we had back then were people like your 23 year old friend; which is rarely a good idea to listen to.
