I'm a 33 year old male, and I've been struggling with anorexia for 11 years. I have been emaciated a few times over those 11 years, I've been overweight a few times over those 11 years, but most of the time I've just been average. But despite being average weight all of the yo-yoing and restricting my food intake has done permanent damage - I have osteoporosis. You can absolutely experience refeeding symptoms at a normal weight. I would second the recommendations here to find a nutritionist who can help you learn what you need to eat - I would also recommend you find a nutritionist who has experience with eating disorders, because they would know how to help you with the unique struggles people with eating disorders experience. Meal plans tailored specifically to my recovery helped me the most, and now that I know what my specific body needs, when I start struggling I can put myself back on my recovery meal plan.
