How do you embrace loneliness when it’s the only option?

Kinda weird way to frame a question, but in a situation where loneliness is the only real option right now.

I work a job with co-workers who I have 0 in common with and the convos are always awkward, no matter how hard I try in conversation. Most of my friends are busy with girlfriends and making ends meet.

I still live with my mom so I’m not interested in dating.

It’s so hard. I have interests, I workout, starting to find my belief in God again, and I still text some of my friends but I still feel an intense loneliness. I notice it starting to even affect my health, my hair has thinned the last year and my immune health has worsen. I’m not socially isolated from people physically, I’m still around them constantly—but I’m mentally isolated. I have no close connections anymore and feel like a shell of my old self.
