ok, im a 15 year old korean who took tkd for a short amount of time (prob. a year) i got to purple belt. its been probably 7 years since i took tkd. since then i got into many fights and lost a whole lot. the reason for me getting into many fights(and losing many) is because my 5th grade year i transferred schools to a all blacks a hispanics school with probably 5 asians in the whole school. In 8th grade many guys that are more built and bigger than me started harrassing my girlfriend, i couldnt do anything b/c they were much bigger than me so i kind of left them alone, but as time passed i got more ticked off so one day when we were switching classes one of the big guys decided to mess with my girlfriend so i went up to him and shoved him, then with my tkd skills from "6 years ago" i decided it would be cool to roundhouse kick him..wow bad move, he stares at me like nothing happened and chokes me and puts me against the wall, eventually the teacher broke it up. now im a freshman in hs and almost got my * kicked a lot of times by bigger football players. im on the track and crosscountry team so i do have some ppl that got my back but i dont know how to defend myself, last week i got my * handed to me by a wrestler, i threw the first punch and knee'd him to the ground, then he tackled me down and did his little wrestling moves on me...since the past week ive been looking into Hapkido,Judo, or boxing.i heard about 90% of fights end up on the ground. i've been wondering which form of self-defense out of the 3 or any self-defense can help me the most to defend myself from those mean bullies lol, sorry the thread had to be so long..thanx for any comments
