NO NO NO!!!!

I am 13 and I really like this girl I asked her out she said maybe I am not sure. I got a little mad and just for some reason just let the opportunity pass me up she said find I guess the answer is no. I flipped out found some new friends now they want to murder me I know because I have heard them talk about it I know I am stronger than them I can curl 80 pounds and bench press 90 pounds. Life just doesn't seem so good now I have no friends everyone hates me because they are scared that I will knock their teeth so far down their mouth they will be s******* them out the next day
