I know the feeling, and it is horrible. It feels like you will never stop feeling that way. The easiest and fastest way to get over someone is by finding someone else.
Try finding another gay guy who you can flirt with so he will possibly like you back and then you will feel so much better. This isn't the best solution but sometimes when I'm feeling this way I like to find a band that I like and start crushing on its members. It takes my mind off the other person.
Other ways to take your mind off are by sleeping and watching funny youtube videos and shows.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
