Maybe a cliché response, but all the times I felt loneliness in my life, I embraced it and even be-friended it. I sat with it, and just let myself feel the feeling. I think that's one of the unique things about being human sometimes; we can feel the full spectrum of human emotions. Emotions come and go; I think someone said that a human emotion lasts for 90 seconds or so. I guess - if loneliness is chronic and reoccurring, I would seek out ways to connect with others, one step at a time; maybe reading a book, listening to a podcast, cooking something for someone, volunteering, join a local walking club, etc.
