Bottled it!

Oh no, what have i done? I bottled my counselling appointment as my ibs has been bad and i was in pain today, but then i asked my counsellor if i deserved to be there? I seem to get really negative when i am ill but feel i am wasting their time. If my health got in the way do you think they would let me back? I'm just scared too because i am still not well enough yet considering i was raped and am still struggling with it. Will they understand? Would you let me back,?
