friend problems😭

I suffer with really bad social anxiety, there is a few people from work who I chat with at work, and few old friends from school who I've spoken to lately, but I can never get past that barrier of just someone I talk to, I have a new baby, and I have no social life, like I have 1 friend who visits now and then. But I can't make any friends, like is it me? Or something I'm doing? I have no idea, I'm not very confident person, but surely that's not the reason people want to meet up. I know this sounds stupid but how do you make friends with people if they don't want to meet up and you have social anxiety?😩
