How did you meet your closest friends?

I am friendless besides my man lolšŸ˜­šŸ˜­ I had one best friend like a sister to me for 10 years but unfortunately she started hanging out with the wrong crowd & dating a man who was just šŸ—‘ļø and I was constantly put in awful / uncomfortable situations so we fizzled out. I was in a toxic relationship before that and had my first child so I never really had time to truly meet people and get out and do things with. I work independently, so I donā€™t meet any coworkers. Iā€™m not in college, etc. so Iā€™m lost on how to find and make close friends if Iā€™m always with my children and mom life lol. Where do you meet people !?
