I'm I the only one?

When I was pregnant I work and had friends. I had my baby on August,and on thoes 3 months I lost all my friend I did not have alot but they stop talking to me and I guess the staying home with the baby is why idk. And my bestfriend now stop talking after 6 years of friendship she stop talking and been petty af on fb. But I just keep my mouth shut. I just feel lonely alot more with my depression is fuck up... I need new friends but my anxiety is bad after I had the baby.... please tell me I'm not the only one
