insecure

I'm insecure about my weight. In my last relationship I gained 60 pounds, and when we broke up I gained another 10. I've lost 4 from eating better and counting my calories the past four days, but I'm so insecure lately. I keep thinking things like "I will not buy new clothes. I am going to fit into my old wardrobe by the end of summer." And "No one will want to date me again until I'm at least 140 lbs or less."
