SAHM no friends (lame, I know)

So I’m writing this in hopes of advice and not judgement.

-I’m a 20 year old full time stay at home mom to a 3 month old... and as much as I adore my son and love being his mama, I can’t help but feel so alone. My childhood friend of 10 years stopped talking to me during my pregnancy, I lost another good friend and we recently just rekindled things but she moved to FL. I have family but I feel no one understands me and my situation. I’ve even tried becoming friends with girls that have kids around the same age as my son since we went to high school together but it’s always the same runaround “we need to hangout!” - Never does. I’m not sure what I’m doing wrong or maybe I’m just not a personable person? I’m not sure. But I’m hoping to at least find mom friends online.. since I clearly have no luck in my city.

I know I shouldn’t worry about having friends but I truly miss having a good conversation with a decent and honest human being.
