First of all I want to say that I'm crying right now. Not because someone hit me hard-otherwise- I almost knocked out my opponent in today's sparring. I'm 16 yrs old doing shotokan karate for more than 1 year. Today was my first serious sparing ( AKA/SHIRO type). It was sparring when 1v1 fight infront of the class. It was my and mine partners time to go infront of whole class. My opponent is 7KYU(+50 yrs old man) and he said to be carefuly. The fight started. I was attacking. After 2 rounds I threw very good and strong GYAKU tsuki into my opponents head. I hit his NOSE. When I heard YAMME! I looked and saw my opponent on his knees. His nose was bleeding. I was like oh my god! Sensei told me to sit and turn my back into opponent. While I was sitting here I saw how my senseis are helping that man. They used medicine and sat him on the chair. While the other guys were sparring, I stood up and ran to that injured guy. I appologised him. He was smiling. When I was putting my clothes on a couple of black belts said that I'm going to be very good in kumite after couple of years. After that sensei told me to be more careful and It's OK-we all are training. After class finished, I started crying. I was in panic, feeling guilty, bad. While I was walking home I cried and blamed myself! That if it would be without sparing gloves? I would knocked him out! It happened in front of the whole class.. All my sensei saw it... Now how I can look into that guy eyes.. I'm not type of guy who enjoys hitting others. I hate myself! I think now that my sparring partner hates me. Who wouldn't? I hit him too hard.. At the moment I want to stop my KARATE training. I need help from you guys! What should I do? Should I stop or continue? Help! Have you had similar situations? I lost motivation for my karate. Also I injured my finger and I can't move it. But it's nothing compared that I have done...
