i turned 22 about 2 months ago. growing up, I've always been chubby - but this is beyond. my clothes don't fit, i get out of breath really easily, and i'm thirsty all the time, so i'm scared it's a sign of diabetes [which runs in my family]. im also 6'' so im taller than everyone i know [including my parents], so just feel like the focus of everyone's attention. i saw a doctor a while ago, and she prescribed anti-depressants, and exercise. I lost about a stone, but then put it all back. i'm sick of yo-yoing. my younger sister's getting engaged in january, and i have to lose weight to fit into a nice dress. i met a guy who was very sweet, but because im paranoid, and didn't believe he could actually like me, i dropped contact. so, suggestions i guess. im joining a gym on monday, but other than going to the gym? weight watchers / cambridge diet didn't work for me. i'm at uni most days, and other days i'm tired all the time and really can't be arsed to cook.
