As best I can. Something we are working on all of the time. Hoping that if I can learn to do it with her then I can learn to do it with other people. I may show it in my body language or I may bring writing in or write it down for her in session. I may say it or draw it or give her a gift or a card showing my feelings (this is only for positive ones really, a nice card which inside reads "right now I am really angry with you" is a but odd!).
Yeah, basically, as best I can in that moment. I am working hard on voicing my thoughts and feelings but we are a long way off from being there yet.
