My boyfriend & I broke up

i feel like my world is falling apart. all i feel like doing is crying, nothing is fun anymore. My mom sais he was just a "high school boyfriend" and that ill get over it, how can i forget 3 years of my life? one day everything just seemed so..wrong. we both felt it, its just after its really over that it really hits me that im not his girlfriend anymore. he was my 1st everything.. and a part of me wished i could forget it all, but another part never wants to forget any of it. I have to cheer at his game on friday..i dont know what im gonna do, evrey1 expects me to do my usual and run into the feild after a good game or comfort him after a bad game. but i cant do that, he will probably find another girl to do that now.. i have to give my promise ring back and i just cant handle all of this right now! as usual my parents dont get it & my friends dont know yet but when they do find out i really hope they can make me feel better like they usually do..
sorry for the vent.
im gonna go eat icecream, thats what single people do i guess. w/e i dont even care if ill be the fat cheerleader, i just dont care anymore! im not dating anyone so i have no reason to be a size 2 anymore. none of it matters.
