Big respect to you not using social media to make connections! I bet millions of people would love to be as you are, were they not completely addicted…
My advice to you, make connections in other ways – go to sports, art, music, hobby, common interests groups. Strike up conversations with strangers in cafes. Do some voluntary work to meet people. Get involved with a community project, or some activism. Find meditation, laughter yoga, healing or yoga classes. Most importantly: think of those around you who really see you, love you, like you, have time for you already, and develop deeper bonds with them. As you develop your autonomy and sense of self, and develop your relationships, your fear of ‘dying alone’ will lessen, as hopefully you will see many people to connect and relate with.
Good luck with it all, and please remember how lovable you are xxxxx
