Insecure about self worth

I used to eat just tiny amounts of food when i was at my dads house and get very hungry and throwing up at my mums house. My father made me feel worthless, so i think that is why. I needed my mum, was hungry for her attention and support, so I ate a lot to compensate for it, but because i never got her attention, I threw the food up again as if I did not deserve it. At times it felt good to throw up because it was like I threw up negative energies from my mum, all her criticism and hate towards me. When I no longer let my parents decide how I felt about my self I took control of my eating and let my self eat without throwing up afterwards. I was no longer insecure about my worth. Thanks to God.
