I'm sorry she had to cancel!! Did she schedule another day before your next regular session? Can you leave her voice mail so you don't have to hold things in forever? or leave emails?
Do you have a doll or bear around that you could have a pretend session with? Or hold one in your head (i do that one all the time). Tell her in your mind what you would say and imagine the sort of things she'd say back to you....
Sunggle up with books, warm blankets, hot chocolate and some stuffies or a cat/pet....
Hope you're alright.
