Maybe you visited a particularly bad group for beginners? Or maybe you were just too anxious, and needed an extra kick so that you'd let them be supportive?

The Toastmasters are a standard advice for a reason. Public speaking is entirely a learnable skill. You quickly get better with practice, but that supportive element of other people is required to overcome strong stage anxiety if you have one.

I think it might be worth it to try approaching one of the members and telling them, "I'm new here, I'm really bad at public speaking and want to get better, but I'm anxious because you all are such expert speakers already; can you help me?". If the Toastmasters group is worth anything, they'll put extra effort to make you feel comfortable.
