Like these guys said fighting is not the answer so try and avoid it. I have been in my share of scraps, I tend to attract *******s. I've never thrown a 1st punch. And I can honestly say even after "winning" a fight you feel like ****. Its just stupid and not worth it at all. Sure your boys will give you props, there your boys they have too, but most ppl frownon it b.c it is dumb.
As far as the "crying" I agree with whoever said there is a difference btwn tearing up and crying. I tear up pretty easy but if I do you better watch out b/c I am about to rage, for me its comes from intense anger/frustration more than anything, its prob similar for you. There isn't much you can do about tearing up. And if you get hit in the nose it WILL happen no matter what. So try and avoid that. crying is a whole other story, its when you get overcome by emotion(sad/scared/depression).
Just avoid fights man, don't take ****, stick up for yourself, but try not to let it escalate to a brawl. I know its hard, I have been pushed several times and called every name in the book but don't let it phase you.
You'd be suprised how many guys are threatened on the inside. Its really another **** test but for guys, they try to get the fear out of you by yelling cursing, pushing..etc. If you don't show it to them it will have an affect on them. More often then not it will simmer down and you can part ways.
Maybe its just me but I have been in situations where ppl start **** and I just stand there, not backing down but not egging it on, at least physically( I do have a smart ass streak in me haha) but more often than not things eventually simmer down.
And as far as confidence, I say hit the weight room a bit. it doesn't take much really, and it will make you more confident. if you start now, you will see a difference by the time summer is over.
