Losing weight without developing an eating disorder?

(Before I start, I’m at no risk of eating an unhealthily low calorie count and I’m not looking to a diagnosis. I know I’m fine, but I grew up with girls who had ED’s, most of the time I was the one making sure they were eating. So I’m sensitive to these kinda feelings within myself. I know this isn’t a therapist’s office, I just wanna know if anyone else can relate.)

I’ve lost almost 40 lbs so far (down from 270) and I’ve started noticing feelings that scare me.

Lately, whenever I eat a meal that I cannot accurately estimate calories/protein for, I feel a genuine anxiety about it. If I eat too much but I can count it, I can make it up, but the not knowing stresses me out.

And yesterday, my family decided they wanted Five Guys for dinner, and for a couple minutes after eating I felt like crying. (This is more so because growing up my parents were on me about losing weight, and now that I actually am they keep offering me unhealthy food and just seem oblivious.)

Anyway, I’m looking for advice on how to keep the discipline without getting these feelings. Tracking these things has really helped me, doing the math and not leaving it up to guess work. But I don’t want to accidentally fall into the wrong mentality. If anyone relates or has any advice I’d appreciate it.
