im so sad :(( my boyfrend cheeted on me and is now dating with my bestest friend ever. i feel so betrayed! on top of that my parents got a divorce three years ago but more recently my grandmother died about a month or so ago. every night i wake up in a cold sweets with night terrers and its really starting to tare me apart like i feel so bad about everyting n its starting to make me feel sad. people teell me its not my fault but it really really really is because i feel so bad. one time my mom got mad at me and maybe not more then 5 months later they got divorced! i always told myself i would never let Daquan and i get like that but now he left me for my friend and i dont know what to do. since the incedent i also gained some wait but my reason for only knowing this is because my brother teases me and i can feel that i get out of breath. he calls me efatty and has my friends at school doing it too, i thought they were my friends but they arent because they wouldnt do that to me!!! :((

on top of that all i have started to do the bad habit of cutting and it really makes me sad that i do this. the final straw was when my dog died and i felt so sad about it. how could my dog leave me we were best friends and i kno my dog would never leave me or take my boyfrend!!! when i cut i use a bobby pin because i dont want to really hurt myself but i kind fo want the emo feeling. i feel super bad at school when i show peeopl what i did but i cant help it and i need people to help me! i hope that if you help me then i wont need help from them.

idk what to do at this point, feel so sad that im almost mad about it. HEEELLLLPPPPP!!!:((((:what:

Showing everyone that you cut won't help you, it will just make it worse. When you start running around with your arms in the air and nice scratches covering them going, "Look everyone! I cut myself. Wanna talk to me?" it just makes people whisper about you and talk about you. You aren't helping yourself at all by doing that, not one bit. You're making it worse. I'm not trying to be mean or anything but it's a usual fact. Most people just don't understand and won't understand and don't want to understand.
Go see a school counsoler. Talk to them about it. It's better to talk to someone who wants to help them picking people out of school and just outright telling them because chances are, it's no skin off those kids teeth when you do. You DO need people to help you but not just random people! You have to learn to pick and choose them wisely. So, of course, a counsoler or parent. Ask your mom to take you to a counsoler so you can talk to one. Kids from divorced parents are often times very scared by the divorce and the con. is usually able to help you out of that rut.
