Dear FabmimiBlog Readers,Should I Worry About My Weight?( My photos).

I think and worry about how much I weigh constantly. I'm a normal weight for my age and height, and I wear a size 14or 16,However, I'm obsessed about what I weigh and I'm always wishing I could lose 10 pounds. I refuse to buy new clothes just in case I lose that 10 pounds and go down a size. Every time I eat I worry if I will gain weight from it.and if I gain or lose a couple of pounds it always returns to where it is now on its own.
I think I'm being irrational, and a huge burden would be lifted from my shoulders if I could let this go. How do I do it or am I Fab and trendy this way?
Your thoughts.
