I don't ride any more and am hopelessly out of touch but I used to be involved in RDA and have heard good things about horse therapy for people with MH issues. I don't want to suggest it without doing some research but couldn't find much on the web for people wanting to do this privately. Can't be too crazily expensive as friend is not working FT at the moment.
It would be S/W London area. Any of you knowledgeable horse people got any ideas?
