I've been there - pulling away and distancing in session, only to get home and feel bereft and alone, and sinking into despair when I realise it's going to be a whole other week until I get another chance to connect. If you quit you'll be cutting yourself off... and it's not easy to keep that mask in place indefinitely. Go back to T, try to open up and tell him all this, and trust him to help you through it.. I think you'll feel so much better - I did, anyway..
