Do i have anger issues?? rage blackouts?

1st of all if you told a kid that you would kill him, i don't think u should b working with kids, it is very bad!! if someone else (an adult) heard u say that i'm pretty sure u wouldn't b helping out with the kids in the karate class, i'm surprised he didn't tell his parents, u do have an anger problem: punching a hole in a wall, not controlling your temper & throwing tantrums are all signs of anger, u need 2 get some counseling, call someone or ask someone u can trust to refer u 2 someone (preferably a trusted adult) parent, aunt/uncle, etc., good luck to you
