  Hi, my psychiatrist suspects bipolar disorder ..... I was depressed for a few months , then everything was more or less fine. In July I was in a very good mood and didn't need very much sleep ... once I didn't sleep all night . I was full of energy ... And yet in between these moods between periods when I'm depressed and very happy I change moods depending on the situation but I'm still in a good or bad mood even if I have mood swings in between....
