I recently got back in touch with an old friend. I found out she has had some trouble during our years apart. She had some problems with drugs and was then diagnosed as bipolar. Please forgive my ignorance but, I know very little about drug addiction or BP. It just seems to me she is always very hyper. On any given day, I could end up receiving 23 texts in a row from her. When I speak with her I don't even have a chance to speak. Sometimes I listen to her on the phone for over an hour and have no idea what she is talking about. She is overly concerned about her beauty and seems to be totally unaware of anything going on in the world. Is this usual for a manic state?

How do I know if this is her mania or if she is using drugs again? Are there any telltale signs of either?

Thanks in advance
