Fear of gaining weight due to my mom's constant nagging?

Power in words: Two things you've connected: there's your fear of gaining weight, and your mom's nagging. Deal with each. Consider that it's not her nagging that feeds your fear, it's how you react to whatever you describe as nagging. You have many other choices. Like, stop calling it nagging. But the key to change is to figure out what you want when it happens, so you can aim yourself and make progress.

See below: One thing to remember -- you can't change your mom, but you can change how you deal with her "nagging". Keep a food diary -- why are you eating what are you eating, your emotions when you ate, and how you felt afterwards. Look at you reactions to others-- do you react the same way to others, like you do to your mom? If you feel overwhelmed, involve the help of the counselor to help you.
