What is wrong with me?

Im not any doctor or anything, but i know what your going through, i am 25 years old, i went through the same thing but from grades 6-9, i am also a heavy set guy it was constant toture from 3 kids i went to school with, they would always shove me talke me to the ground, punch me in the face arm leg neck groin, and kick too, i would also get threatened to do things for them, and alway cause physical harm, i once spent 2 days in the hospital for a broken wrist cause one of the kids hit me with a baseball bat "accidentally" but had a huge smirk on his face it was hell for me, i am sorry for what the did, i never wanted to leave the house after the first few months of being bullied, my parents would have to drag me out of the house, i was a affriad to tell anyone, but one day when i was in 9th grade ill never forget this, this was the last straw, ill never forget his name, and i hate him for the rest of my life, this kid bobby saw me walking to bathroom one day during a school period i walked in the bathroom and was using the urinal, i didn't notice it was bobby till i feel to the ground in pain, he had kicked me in my lower back while i was peeing i was in pain ask my groin had hit the back of the urinal hard, after i was on the floor i looked up to notice him again and kicked me straight in the groin, i guess you could say i got lucky, but i guess a ping student heard a comotion in the bath room, came in and saw me on the ground in tears, tell him to leave me alone, he ran to a teacher and yelled, as the teacher was coming in to the bathroom he say bobby kick me repeaditly (2-3 times i think) in the stomach, and immeaditly pulled him off of me and said your in alot of trouble, the principal come up say what happend called for an ambulance and the authorities, i was crying and in severe pain, as i was in the hospital room, i told my parents, the teachers, and the police everything and how long the abuse was going on, my parents figured out then thats why i never wanted to go to school, i pressed charges on bobby, and he went to juvinelle hall for 6 monthes which he got what he deserved and realized what he was doing was not ok and constantly during the hearing apoligizing to me crying saying how bad he felt, which i never beleived it, and the other 2 kids were expelled from school, it was a releif to see something being done, well what happend was i went to see a psychiatrist, which was a life saver for me, i saw him twice a week for about 7 months, he helped me out so much, and made me feel great and good about myself, and told me to find something i loved to do, well i started taking self defense cles after that all happend, i mean i still cringe and tear up when i think of that day it was hard and is still hard but i don't let it bother me, after all this i graduated 5th in my cl, was a central m all star pitcher my senior year, and haven't seen bobby since he went to juvinelle hall, id say for you sake as you seem to be getting it worse then i did, but id say go see a psychiatrist and tell them everything, talking about it to people and getting advice is very helpful, and can almost save you, it saved me and also doing the self defense cles i explained to my teacher what had happen to me and he was disgusted with all that happend, and helped me out teaching me self defense, and most important of all self confidence and pride, to this day i am still doing my self dense (kenpo - ju jujisto) and i am 2nd degree black belt and teaching karate at the school i started in, i feel like i can make a diffirence in some kids lives that are going through the exact thing as i did, to see kids in middle/high school learning the values we teach in karate is great, im not teaching them to go out and hurt people but better yet to avoid fighting, and if you can't that you know how to protect your self, but i am sorry for your pain and torment those kids have being doing to you, but i say still persue the authorities with those kids, i know that they just ped an anti-bulling law in my state which now the bully any age can be tried as an adult depending on the severity of the case , but some advice from me to you, stay as far as you can even if it means changing school, but see a psychiatrist it will help, it helped me and many other people, they are safe and will never hurt you, i hope everything goes well for you, i sincirely hope your ok, and i hope i gave you that push to go get help...
