Looking for some motivating friends

Hi everyone. Names Shelley. I'm 23 years old and about 60 pounds overweight. I've tried to diet in earnest probably about six times, but I can't ever keep it up. The last time around I lost 20 pounds, mostly from using this app on my iPod, but I gained it all back. I wanted to lose 20 pounds in order to fit into a special dress for a friends wedding, but instead of losing it, I gained 5 pounds. A few days ago, I went to the store to buy a swimsuit because I've become too heavy for mine. It was the most frustrating experience I've ever had shopping for clothes. In addition to being overweight, I have a large bust... I'm a double GG to be exact, so swim wear is the most frustrating clothing to find. I threw a huge fit in the middle of the store and wouldn't come out of the dressing room. I burst into tears and could not stop sobbing and I actually told myself, "I am going to hang myself when I get home."

There's no reason for me to be young and depressed like this. I just have to get it right this time. I've always liked this app, but it would be nice to meet people in similar situations who will encourage me, and whom I also can encourage.
