✔ 最佳答案
I guess in your case you don't. Noone can fix this for you. You got to train hard and quit listening to all your 'friends' discouraging you who have never come any closer to a martial art than watching UFC. So as long as do don't do either you definitely should refrain from fighting a big person, or better yet don't fight at all since you are not only easily influenced by others who don't know but also seem to get easily intimidated.
