I need advice

I'm at a point in my (40f) life where it's clear I'm going to be totally alone. I have no friends or family and finding a partner is an impossible task. No one wants me so I'm trying to accept this reality. How do I do this? How do I give up my desire for genuine, deep connections with others? How do I get rid of the pain and hurt it causes me when another connection fails? How do I stop looking around at my solitude and not completely internalize it? If I had even one person who cared about me, it'd be a lot easier to feel secure in my ability to go through life alone. Idk. I'm just lost and hoping maybe someone else has figured this out.
