I never had those last appointments so I will probably be no help for you. I know medications should never be the only answer but do you have any prescriptions for anxiety meds? If he is like either of my Ts, I am strongly discouraged from taking them before an appointment and if I choose to they ask that I tell them. I think you should tLe something so you can get through.
I would keep the next three appointments on the lighter side. maybe discuss what you have accomplished together, your goals for your therapeutic future, what he recommends you work on in the future (if you care about his input). I would tell kim immediately how your feeling and be open about the vomiting and anything else. This will allow him to help you.
