I think I am going crazy..what should I do?

Dude I Sorta know what you mean and this is a plan that might not work but like you said with your phrase. No one can tell you what to do and if someone says move on and you listen you are stupid :) Basically buddy If i were in your situation then it would be hard but obviously you need to tell her how you feel before you leave.If you can't do it in person or she wont meet you, then write a letter. Not a long 6 page sloppy letter just to let her know that you liked her and you will miss her and post it through her door a week or so before you leave. If she does like you the obvious thing is she will call you and fairy tale will take place but also she may think your a bit wierd. I did the same sort of thing except I knew this girl for two years and I was about to move and I never told her how I felt but I wrote her a short letter and she rang me the same night saying that she thought I was amazing and sweet but she didnt feel the same way (which was fair enough) but she still wanted to keep in contact and we have been meeting up every break from school we get and now we are really good friends. It's hard to get past the feelings but it takes time. Well done for actually posting this and i knwo what you mean about your friends thinking your a retard. I feel the same sometimes. I hope this helped a little and let me know what you decide to do. Email me on my hotmail account mnmleg@hotmail.co.uk :) I really want to know how you get on :)
