Whats going on inside me?

Saturday I went to a party and was totally at ease talking to the girls there, and ended up kissing one, and this girl just doesn't get out of my head, Ive thought of her since the other day morning, and there is a music that makes me remeber her. I want her so far and even feel like crying cause of that coz she lives too far away from me :"(. wat do I do?? Is there anything wrong? never felt it before, just cant forget her kiss.... holy shi.t what is it/??
