I'm sick of him

he hurt me so bad. i mean we were so close to dating and i don't know what happened after wards. i mean this year hes so confusing before a level two OK is now college level or beyond. i don't understand it, it confuses me and it makes me so mad. I'm so confused and i really need help. shall i laugh or not. or yell or not. ignore or stay friends. my head hurts just from thinking about it and the whole situation. and then this year my best friend in the whole wide world just leaves me without telling me. then he keeps avoiding me. i swear this year isn't going to be great. plus homecoming is coming up and i want to go but the only thing standing in my way is my mom. somehow i have to convince her to let me go. so far i've done very single assignments. all of the essays and geometry homework no i'm just so confused about what i should do. someone please help me. i'm really lost and now have a massive headache. thanks.
