this is no troll thread so please dont slay on me for this..im just coming to my fellow sherdogers for help. Im 6 foot 3. i weigh 150 pounds......i have a weak chin ( i think ). im 18 years old and since i was 16 all iv wanted to do was fight. i love every thing about fighting...what should i do???? O! and about the " weak Chin ".. a few years back when i was in high school. this black guy who was pretty bigger than i always made fun of me, he used to come up to me and jump..you know like when people fake like they'er about to punch you..for some reason one day i got the balls to stand up to him and i told him ya know " fuck you, you wont really do it "...my plan was to not flinch when he acted like he was goin to punch me....well i did, but he acctually caught me with a nasty right hook...i saw my vision go out into just pure yellow light and my ears started ringing. i hit the ground and was down for about 3 seconds. but when i got up i was fine. but ever since then iv always wanted to be a fighter but im just scared to get hit..cause of my chin i guess. what should i do???? any help would be nice and i PROMISE THIS IS NOT A TROLL POST!.
