Bipolar Disorder Support Group
Bipolar disorder is not just a single disorder, but a category of mood disorders marked by periods of abnormally high energy and euphoria, often accompanied by bouts of clinical depression. This is the place to talk about your experience with bipolar disorder, learn from others' experiences, and find support.

Here is what I think...You need to look at the friendship you have had over the past 20 years. Look at the relationship and ask yourself this...
Is the relationship toxic for you?
Yes we beepers can be difficult to get along with, and relationships are hard for us. It sounds to me like you have know her for a long time and she sees you as a part of her support structure and that is important to her. Sit back and look at the whole picture. If this relationship is toxic then perhaps you need to take yourself out of the situation.
