I think lolagrace's advice is really good here. Based on your previous postings I feel sure you would regret it and be upset if you did not go to your appointment tomorrow. Plus if your T has a 24-hour notice policy for cancellations like many do, you'd probably have to pay for it anyway. So might as well go and see what he says about weekly appointments and about ways to cope when you have to go longer. If he turns out not to be helpful, you can always look for another therapist, but why not keep what you've got until you find one?
