Is it normal to not be able to forget something thats killing me?

ok.. so in my tennis class, there was this guy.. really awesome guy.. one of the only people in the class that were in any of my classes.. but immediately, i knew he was out of my league.. so i backed off. then, a few weeks later, we were out on the courts, of course he was there, playing really well. this girl next to me told one of her friends that he was really good at tennis.. and i got to thinking that maybe i could just have a small, tiny crush on him.. just cause. i knew lots of other girls liked him, and i knew he liked some other girl, so i tried not to get to attached. over the months(it was about november) i was really obsessed with him.. he was always on my mind. there was not one paper in my binder that did not have his initials, or heart or something on it. i actually started getting up in the morning, i had a reason to be happy. then i heard he was moving.. so i got really sad.. but i figured that he would be moving at the end of the year.. so i didnt worry about it too much, it slipped my mind. then one day, mid november, i heard him talking about soccer, and the up coming season. one of his friends asked him if he was going to try out for the team, and he said no. i was baffled, soccer was his favorite sport, and he was REALLY good at it. he said he was moving at the end of the semester.. to wisconsin!!i was destroyed.. i was devastated. he was just so perfect!! i became depressed.. my grades went down, and all i drew were broken hearts. i never got up before 7(i have to leave for school at 7:15). i still remember his last day.. memories flooded back to me.. i stayed in front of the school until i saw him leave. now.. i am trying to get on with my life.. but i cant. i feel like im betraying him. because of him.. my life was actually.. happy.. i wasnt all depressed for once. there are so many things i wish i had told him..</3
