You could always think about bringing the shortened appointments up to her, maybe sometime in the future when you feel more comfortable. Your therapist should be open to hearing anything from you. Therapy is supposed to be like that. But I understand your comfort level has to be there too.
I am distressed to hear that you are thinking about suicide more and more. It is an indication that you are depressed and the treatment you are getting needs changed. It could also be that the morphine is making you feel worse. Morphine is a depressant and can affect your thoughts and feelings more than you realize. Does your therapist know how you feel? Does she know about the letter to your daughter?
