I feel the same way - I'm only 5'2" though -- I weigh 140, but for me, it stacks up and to be honest, I'm tired of buying new clothes.
The depression is the worst part. And, not knowing if anyone else feels the same way that you do --
I try to watch my weight, and I try to exercise, but I am on estrogen replacement (premature hysterectomy) and synthroid (thyroid problems) and I can gain 5 pounds in one day. It's absolutely devastating.
Hang in there, Beck. I keep hoping that someday I will make it back to my ideal weight -- I'm not sure if it will happen, but at this point - I'd just be happy to feel good about me - right where I am.
