You need another T, or this one needs a wake up call. Therapy is for YOU and if the client doesn't think it's going indepth enough, that's a big flashing sign to me!

Therapy can help with moderating depression, but only if you've got a T you can feel comfortable working with. It doesn't sound like this one is working out for you.

You could email the couples T, but you could find another T altogether. Don't feel bad about leaving this T, you need to do whats good for YOU.
