Maybe this is my chance!

Hi Everyone ~ I am new, this is my second day on myfitnesspal.com. I actually read about this website in a Fitness magazine and thought maybe it could help me on my journey to losing weight. I've been on again off again for years now. I don't really have any friends doing this with me and my husband tends to just be a supporter but in my opinion not enough to keep me motivated a lot of times.
I have always been activate. In high school I joined every sport I could, I was on a swim team for 4 years and placed 8th place out of 200 girls in my age group. I was extremely active, healthy and skinny (in my mom's opinion toooo skinny!) I never had to worry about what I ate or if I slept in one day instead of working out.
Now I worry every day, I think about what I'm eating and how this will effect me later, I workout and feel like it's never enough. I have been at 165-170 for about 8 years now and I'm sick of it. I keep telling myself "this is my day! I'm going to start over today and stay on the wagon and lose that weight"... but it never happens.
If you feel like your going through the same thing as me, please add me as a friend, I can use all the friends and support I can get.
thanks all!
