Just saying, my weight was technically in the normal range (a majority of the time I was experiencing my most severe symptoms) but I was still having problems with eating. Disordered eating is not synonymous with an unhealthy weight. I know you're having legitimate health issues so I won't say whether your issues are from disordered eating or not though. I'm just speaking from my own experience with and knowledge of a definitive eating disorder.

eta: It's better to look at other physical symptoms, although I do realize it's hard to know cause vs effect in your situation.
