I’m not sure what I have

I’ve been to the doctors multiple times throughout my life for not getting enough nutrition. As a kid I’ve had a really hard time getting food at my moms. So I’d always be hungry. But when I went to my dads every other weekend, and there was food. I could never get all of it down. Maybe by like half a plate of any meal, or less sometimes. I’d start gagging. And I’ve been like that ever since. It’s never nauseating, it’s more like i think about it so much. When I put the food to my mouth i just automatically do it. It’s not as bad when i was a kid. But my eating habits are almost worse at this point. I go hours with out eating. And eat a whole bunch of foods that I probably shouldn’t be eating. I rarely ever cook a good meal and get on top of my stuff. And it’s honestly because of my daughter. When I was pregnant with her, I was prescribed a whole mountain of boosts nutritional drinks. I wasn’t even able to finish all of them. I’d really just like an input from people who are diagnosed with anything and if they go through this.
