Lonely, no friends!!!

I am in serious need of mom friends...my husband works from early morning to 8pm and I am home with my toddler.  I am pregnant with baby number 2 and suddenly finding myself really lonely.  My best friend never keeps in touch anymore and always says she's so busy with work she can't hang out but posts pictures of herself in NYC with friends.  Does anyone else on here feel this way? How can I make mommy friends?
