> many of you find alone-ness to be natural, and even required

You can hear that from people who are not truly alone, but have more attention from their closest than they need.

The answer to your question - "Don't". Shift your priorities, reshape your life, change your place of living if needed, but don't be alone. This shit will kill you.

Maybe you can discover other ways to be connected with meaninful people – not necessarily the closest/relatives ones - through sports, volunteering, local neighborhood initiatives. If needed, spend more money on it, travel to other countries to meet people that you care about. Anything that leads to real human hug will work. I measure unloneliness progress in the average number of human hugs per day :). Optimize your life for that.

Whatever you do, refuse to have the life where you're alone.
