When I was a therapist, I loved working in person; it seemed so much easier to feel what people were feeling and think about that (they hadn't invented mirror neurons back then, so I had to rely on psychodynamic theory instead, which was terribly upsetting for anyone with an enquiringly sciency mind).
But lets face it, most health problems mean we have extra problems managing to sort out appointments and get ourselves there on time and in a fit state to use them. In fact there's a whole brand of therapy theory devoted just to how to interpret such issues!
So what about support online? I saw a recent rash of posts about it and, of course, most of my life is now lived online. It's certainly got it's limitations - definitely no empathising with people based on their none verbal communication, so it's hard if someone can't or won't talk much (maybe snapchat therapy will become a thing for online art therapists?!) but it's clearly much more accessible in practical ways.
Do you use any online methods? I've always found twitter incredibly limiting, but in the Telegraph today there's a man who found it to be wonderful for his depression!
