How do you deal with loneliness?

For sex, you rub one out.

For food, you don't need a partner.

For entertainment, you do what gives you joy.

But for when everything is silent, you are 50 and all by yourself?

This is not meant to be against MGTOW. This is the most important question, because this is what women are supposed to fill(but often don't).

How do you approach this inner feeling of lack?
