how do i differentiate a diet from a disordered behaviour ? is this food freedom or a binge?

hi i’m 22f and i just thought “fuck i’m tired of restricting” and bought myself loads of snacks that i’ve denied myself for months. ate a lot of them (but not all - stopped when i felt “done” with them) and now want to order a takeaway.

I have no idea if:

a) i’m finally choosing food freedom & healing from my restrictive patterns.

b) i’m binging and don’t realise i’m about to begin a binge-restrict cycle.

a) i’m just quitting a regular diet bc nobody enjoys dieting and this is all an excuse bc i want out.

i don’t really know what context matters here but:

-i had only eaten one 300 cal meal for the day before this

-i haven’t eaten indulgent food without thinking about how to exercise it off or skip meals to compensate for it in so long. & i usually only indulge in social settings where i kind of have to. and then restrict when i’m alone to compensate. just wanted to eat alone and enjoy it for once.

-i’m 1.5kg/3lb away from an underweight bmi which is what i’ve been aiming for
