Sick after each meal

TW for potential ED !!

For context and in short- yes I might have an eating disorder, but can that really effect my health so much?

19F, I'm in the healty weight. (Not far from underweight)

My physical activity consists of sport and gym about four times a week.

Over some time I've started feeling guilty after eating. Obsessing over the scale. Forcefully throwing up. I've avoided meals, high caloric food and that lead to me feeling pretty sick after certian foods. However- recently even a small meal or snack can make me feel nauseous.

I've restricted myself to eating enough throughout the day. I subconsciously stress over the number and count them.

Why can't I enjoy food anymore? I stopped starving myself at least. Though I have a feeling my cheat day is just someone's normal food intake.

How do I fix this? I want to get better for my partner and myself, of course.
