If you’re socially isolated, why?

My fam passed away, I work, I'm a single mom... I'm too tired, don't have time and people don't want you unless you're perfect for them. You have to dress right, talk about the right things, have the right tone and posture and ugh... plus I just like being alone. It's quiet and uncomplicated. I'm not against other people in my life, but I haven't met anyone that accepts me.
