Nonstop thinking about her

Well i cant really stop thinking about this girl i met. it started on saturday when i met her for the first time she was like :O, i relaxed and started a conversation with her and got to no her abit more it was fun and all BUT
once they left i was sooO dumb andd forgot to get her email and the worst thing is she was leaving today and i didnt manage to get her email again! Now im stuck thinking of her every single day with a picture of her and me on the first day.

I really like her and all but come on shes lives quite far away (UK) so ever since that day when i met her i cant stop thinking of her espeacially when i listen to Deep R&B songs and some reason im feeling abit umm “weak” in school and at home. I really dont want 2 cut her away or anything just want my “weak” feelings gone. Right now my only suggestion is to see her again in person other then that im smoked.

Anyone got any advice? cause ive never felt like this before
