I too have a hard time talking about some feelings and I am incorporating art into my therapy. I'm not doing the art in session but but doing the art at home and then brining it in to discuss (tomorrow is going to be difficult - i drew a pic of 'the girl' and her feelings). I couldn't draw etc in front of my t as I'm an artist and I can't translate what I'm feeling through drawing in the presence of another person (when the feelings are difficult ) (i would edit things in addition to being overly critical of my work).

As WeePow mentioned if you can draw in session with an objective/focus then great or perhaps try it at home and bring it with you?
