BAD DAY!!!!!!!!

I'm so frustrated right now I can't even get my thoughts together. First I went to the gym at 6 this morning trying to get at it....the stupid trainer I had do my bf came over to me and said he thinks he made a mistake while getting my measurements and wanted to do them again, I said ok...well first my weight is up to 229lbs up 2lbs and my bf is 16 %$#@^& %!!!!!!!!!! I can't compete in a show with 16% bf!!!!! can't believe this...what am I doing wrong????? I got so mad I started to leave, but I didn't (i should have) because trying to work out harder I hurt my stupid back...I'm 10 weeks out from the Oct show and I got 16% bf and a tweaked back....I am mad at myself....what am I doing wrong or maybe I should say..what am I not doing.....I'm really frustrated and confused!! HELP!!!!
