This is all too true Butters!
It's doubly hurtful when the professional who is supposed to help you doesn't truly listen to what you're saying and insists you're on the proper course, even though you're sliding. This has happened with my Wife, who has Bipolar Disorder. Her psychiatrist insists that she only take lithium for this, as it's "the treatment". This is despite the fact that she has told him that she doesn't think it's working properly. He just ups her amount instead of looking into alternatives. There are many alternatives to Lithium, especially for those who are on the more depressive side of the Bipolar scale. She's finally got up the nerve to confront the doctor and demand different treatment, as the lithium really isn't helping her anymore.
It's very disheartening being told by your professional that you're wrong, keep on keeping on. This dink even told me one time, in full earshot of her, "don't listen to her about this, it's all in her head". Took my entire self-control to keep from knocking the guy out. I wanted her to change psychiatrists, but there's such a shortage in Ottawa that if you have one, you can't get a different one unless there's a complete breakdown and even then, you're on a waiting list for quite some time. This is why we needed the psychologist, someone who she can talk to.
