Not free though. I went to therapy/counseling through a church. Super cheap! But still not free. I feel like it should be free though.

I think cheap makes more sense than free. Trained therapists gotta make a living. If it's just volunteers doing group therapy things it would still take time to set up and resources to maintain. If there's food or drink available then that costs something too.
