A friendis staying with me and I have noticed a marked increase in her erratic behaviour and moods. I am really worried and would like some advice please. When she was up, her mood was heightened for a short period of time, but then it seems to be followed by a very sudden change (within minutes) where when asked what was happening, she complained of being dizzy and she went very quiet all of a sudden. She asked to be left alone but due to what was happening (and experience with her in the past) I decided to sit with her throughout it. She seemed confused and spaced out and soon after this she stopped responding to me at all (I persisted with trying to talk to her as I was quite concerned) and she remained in this state for quite a while and seemed to be just staring at nothing. Then her mood appeared to change again. After some minutes, she was responding quite harshly to me and ran outside where she became quite angry that I would not "leave her alone." This "cycle" happened several times thoughout the time (usually at night) while she has been staying with me. It was a definate happy and outgoing mood, very sudden change to a blank stare where she was not responding and another sudden change to "angry" which lasted for different lengths. I do not know what she was angry at, as she seemed quite happy only moments earlier. After she calmed down, she was quite apologetic and seemed to be genuinely sad and sorry for her outbursts. I found that she did not remember most of the outbursts which concerned me most of all. It was like she was a totally different person and it all happened so quickly.
Do you have any guesses as to what these symptoms may point to?
