Yes, I've heard bad things about Craigslist too, but have never experienced any in about 10 years of using it aside from the case of emailing someone and not hearing back, which I don't figure is a big deal. Craigslist has specific sections, so you can go to the "Platonic Only" category for your area and post there, no need to read or be involved in the Romance sections. It is all anonymous to start with, so you can screen all the replies, and just respond if you hear back from someone that seems like a good fit.

I would encourage you to try talking yourself into something instead of out of it. Maybe list all the potential benefits. Sometimes anxiety can help convince us to stay stuck when it's not in our best interest.

Maybe you'll have some luck with the mental health clinic, I'm not sure about those.

Also, do you have any service like Meetup where you are: http://www.meetup.com/ Ours features a lot of free groups and activities around virtually every topic. Many have web pages so you can learn a bit first before going in person.

P.S. There are a lot of concrete tools for anxiety. If your therapist won't work on tools with you, have you considered a workbook, or other diy option as an adjunct?
