I've been low carb for many, many years now. Your interest in cooking will return. At least it did for me, although it sort of waxes and wanes.

I think a lot of what people experience early on is a physiological withdrawal from carbohydrates, especially wheat, that makes them a little forlorn. Maybe their brains have been overstimulated by all the opioids from wheat and so they aren't think about their next fix all the time.

That can leave a little void, like it does when you quit smoking and your hands feel empty and things just don't seem right for a while.
