Again, I would steer clear of leaning to or away from any particular diagnosis unless you are medically qualified to do so and have met the patient in person. All Tarot can really tell you, is that a particular individual might be in need of professional help.Well we will never know what is true or not, that's just where my mind goes. Also somebody else mentioned possible schizophrenia & about The Moon not thinking clearly. That could indicate possible delusion/psychosis which is part of schizophrenia. Going along with what I said about the mysterious "hidden side" you don't really know what's going on in their mind.
I would lean more towards Bipolar if there were also more positive cards also to signify more of the depression/mania.
