How hurtful. Sometimes psychiatriasts forget they are themselves only human. I love what LostSavant said about asking to record your sessions. That's brilliant. Keep them on their toes. I agree with Perna on the journal as well. If you keep track of your sleep patterns it can bring a lot of clarity to the situation. It might even give your therapist some insight into what medications would be best suited for you. Though she sounds a little flippant in that regard. The more you come in with hard facts, the better she can serve you. It might also give you an element of control as you will be able to see helpful patterns yourself.
I'm sorry you are feeling a burden on everyone. I can relate to that as I have been out of work for two years. Currently I'm sleeping on a bed in my sister's kitchenette. I hope these ideas work for you. I'm thinking of applying them to myself. They were good ideas.

Be happy. Hug
