I agree that your post was a little blunt, Lewis, even though I understood the real desire to help out and to get to the bottom of the problem. The wording could have been a little different.
I'd say that, Romantic, we ARE here for you and you can disclose as much as you like, giving us a bit of the details will help to find some practical solutions. If all else fails, just talking about how you're feeling may help you to alleviate the pain.
Remorse, as Rainbowmum said, is probably a good thing. It means you're not completely inured to that feeling, the feeling that you need to correct something.
Have you gone and told someone that you were gay? Is that it? Have you gone and asked someone to be your boyfriend and been rejected? It sounds like you've just experienced the opening of Pandora's box and are not sure how to close the box again. Maybe some good will come of it, because it needed to come out, such was the pressure inside.
The best we can do, as your friends on this site, it to try guessing what happened and ask you a few questions. Is that all right with you, Romantic?
Take care, find that courage and stay with us.
