hey guys I'm new to this app and I'm looking for a change!
Add me as a friend I could really use the help, support, opinions, advice, etc.
I am 5'6 & a half and I weigh 182 lbs.. I'm looking to lose 50 lbs. about two years ago is when I started gaining weight. I'm now 19 and I want my old body back.. I have always been thinker on the lower half of my body but now I'm thicker everywhere! I hate it.. It's time for a change! I want to be able to wear a two piece bathing suit this summer!!
