It's tough in a group of 13 . My MG was originally about 10 and settled down to 7 of us that would meet regularly.
Is there anyone in the group who you think you could click with? If you keep going you may find that someone is feeling the same as you. It's quite common for MG to split into different groups.
It would be great if you could meet other people with kids around the same age as your little one, next time you see your MCHN see if she knows anyone or perhaps another group you could join.
Other things to try is a Play Group?
Marcellus is right..you can meet wonderful Men and Women here on BB, if you can't make the High Tea, perhaps put a post up in the Members area in WA state and see who lives in your area for meet up.
