I've always been a little chubby, started when I was a child. I will never think of me as a thin person, I'm just not built that way, and I'm fine with that, I don't want to be thin. Just thinner.
Also want to add I don't buy into the reason you are not losing is that your body is in "starvation" mode. If that were the case there would be no such thing as girls dying from anorexia, or people in third world countries with no food who literally die of starvation
