Ok so my school had a dance today because T-CAP was over and they want us to relax and stuff but not for me....I'm really really sad and there is this tight feeling inside of me no matter how much I tried to block it out it keeps coming back EVEN WITH KPOP!! I regret ever going to that dance

My crush....Elijah Fults...... He was dancing with another girl.... Hugging her...swaying side to side on a slow song.... I almost bursted out there.... It was so so so sad..... I felt like my world had totaly collaps..... But I didn't want to think about that... Because next year I'm moving anyway so not having a relationship is the best right now... We only have 3 weeks of school left so I don't want to date anyone 5 guys already asked me out and I rejected them all one of them was my best guy friend, jake, Not thinking about that moment about Eli and that girl I tried to have fun with my friends and I did but that feeling still lingers around..... And when I got home.... Things got worse...

Nathan Blanton, my old crush, was dating one of the girls that I knew I didn't hate her or anything we just don't know each other that well I was happy for them but that little feeling in my heart just spread out and I was so so so so so so sad.... I felt like bursting out right there! On the spot! I told my big sis and she told me to forget about it and try to move on since I already left Alabama( where nathan is living) and I'm about to move away from Tenessee( where I'm curently living and where Eli is too). She might think that is easy but it's totally not!, and as I am writing this down right now that feeling stills lingers around my chest..... I really regret my decision about going to that stupid dance 

What do you think I should do? Should I forget about it or face with it? I really your oppinion
