Not wanting to eat dinner with parents but feel bad

Hi there,

I have been feeling really not wanting to eat dinner to lose weight or sometimes I am just not hungry. But I feel bad for not wanting to eat because my parents cook dinners for me. I end up going downstairs to eat but end up feeling resentful and hating myself for forcing myself to eat

C: I am not hungry and don’t want to eat dinner
T: my parents will think I am not enjoying their meals
f: feeling anxious and think that I am a bad daughter
A: force myself to go down and secretly feeling resentful about being there and eating
R:weight gain and feeling resentment, off the plan

How can I get rid of this feeling? Am I doing it that can hurt my parents’ feeling.
