I saw this in a magazine and could totally relate.
"When I was overweight it was like I just blended into the background, but then I started getting thin and all of a sudden people were noticing me."
Now I realize that could be a good thing. Instead my feelings were (1) "Where were you before?" "All of a sudden you like me now" (2) all the new attention is difficult to handle. Now I realize my ISSUES are in my head and I basically had to get over myself. Change is hard, even good change.
One of the best things about losing the weight (there are many) is feeling normal. That's a good feeling. I'm not the fattest person in the room. And yes, I used to always notice that.
