I know how you feel, I'm in a situation like that (sord of ) About 4 months ago I switched classes from my best friend, I was so sad, 4 months I'm still sad, she does not care, she dose not care that I care or that I'm moving, you know why? Because, maybe she did care in the first place but put in a situation you can see people's true colors, she was never worth caring about, and if you don't let go, you'll feel like a looser, but if you do still your not you have a lot of feeling like me, those 2 days must of felt like a month, my advice try as hard as you can no matter how scared you are until you can't no more,if she dosent she's not worth it just trust me.
