I understand loneliness better, it's another form of hunger.

So if you're not taking in nourishing foods on a constant basis, your body is just asking for more, in a pitiful attempt to eventually find the nutrients it needs.
Similarly with companionship, if it's not fulfilling, one is keep on feeling "hungry", empty.. despite there might be company, "food" , but if it's not the nourishing kind, one keeps on feeling hungry, lonely.

It's tricky when trying to change patterns. It's easier to fall back to the same wrong types of foods.
Remain alert and aware. We are doing this, we can do this.
