I think that there is plenty of research out there suggesting that depression and bipolar are biochemical diseases. They are real, medical diseases. Just as one cannot talk oneself out of diabetes, one cannot talk oneself out of depression and bipolar. However, there is value in working on ingrainded thinking patterns which can contribute to depression. I have found that working on my thinking using CBT has been helpful in my life, along with medication.

It is unfortunate that your son doesn't understand your illness. I wonder if he would be willing to go to a therapy session with you to gain some understanding of your illness? There may be some underlying resentment towards you and your illness that is fueling his feelings. Take care!
