IT WILL BE HARD TO LOSE A LOT OF WEIGHT IN 4 WEEKS. MY PREDICAMINT WAS BASICALLY THE SAME AS YOURES. MY FRIEND WAS HAVING A POOL PARTY HIS MOM USED TO ONLY LET GUYS COME SO I DIDNT WORRY ABOUT MY WEIGHT PROBLEM AT HIS PARTIES. GIRLS ARE COMING THIS YEAR. I TRIED LOSING A LOT OF WEIGHT FAST IT MADE ME GET SICK. SO START A DIET BUT DONT WORRY IF PEOPLE SAY SOMTHING. JUST GO AND HAVE FUN. P.S. YOU WILL BE SUPRISED HOW MUCH BETTER A COUPLE OF POUNDS LOST CAME MAKE YOU LOOK. YOU WILL LOSEA FEW IN A MONTH.
