Need a buddy

Hi there! I'm Christina. I'm 27 and I weigh 176 and I hate it! The odd thing is my clothes still fit but their very snug and I'm jigglier than I have been in my early twenties. I'm so angry at myself. I used to play tennis and weigh 150 but it seems like once I got past 25 everything slowed down. I have really been trying to lose weight but I haven't been doing well. I'm so bummed and embarrassed of my body. I work out and eat right but still cannot lose the weight. I don't know what else to do. I would love to have a fitness buddy around my age to motivate me and in turn I could do the same.
