I know that it may be outrageous to suggest that anxiety disorders or any disorder in fact is contagious, however I have a friend who suffers from many psychological problems. She has never been diagnosed, in fact she went to see a psychologist, and revealed to me that she was able to "convince" him that she was fine, although she knew that she had a problem and that is the reason she consulted a therapist.
Initially, I had confided in her that I too had a few "fears" however this sparked her to become more open with me. Lately, I feel as though I have become more anxious about life and also depressed. We have been friends for more than a decade however I feel like sometimes I am unable to help her without also losing my own mind. Her problems allow me to feel like my own are minor and sometimes I feel like I have acquired her thinking processes. I'm not trying to "blame" her for my problems and I may have always had the capacity, however I can't help feeling that her anxiety (perhaps bipolar disorder) is affecting me. How can I be a helpful friend and yet still remain psychologically sound?
