There are so many ways to not be lonely. Checkout meetup dot com, they've got so many interest groups. Knitting, photography, philosphy, screenwriting... or start your own interest. I don't see a lot of landscaping and spit-up groups on there. I'm sure your kid would love to know what your hobbies and interests are! :) I started knitting and joined a stitch-n-b group... that's certainly a crowd of mothers who think - they met online, they talk politics, & kids are welcome to come to the weekly meeting.
There's so much out there to do! And lots of people in your same position that would like to find interesting people to hang with.
