Isolation is painful, I know that very well. There is a vast difference between having no one in your life and feeling incapable of being ok without company. People need community, we are social beings. The best advice I have for seeking friendship is to join groups you have affinity with. If you’re particularly interested in politics, art, music, movies, gardening, anime, 3D printing, TTRPGs, whatever it is you love spending time doing, find people in your area who get together to do those things and try to join them.
If, on the other hand, you have friends and community but still can’t stand the time you spend alone, address what about being by yourself creates that anxiety? What are you getting from constant company that you don’t have alone?
Fair, I tend to think in terms of affinity rather than ranking, i have high affinity with some people and less with others. it’s not about rank, it’s about… Vibes? I guess? There’s probably a better word but codes it what comes to mind.
