The case of numbing the loneliness has so many option. But yet, the safest one that can be chosen is to make yourself busy in a positive way (work, exercise, etc).

Unfortunately, to choose that does not really solve the numbing at all. In fact, worsen it because you're avoiding the reality that your soul and body still need someone (physically if possible) on your side.

That is why, to choose to be alone is really a hard decision that someone might already decided from their will.
