I can definately relate. I was diagnosed Bipolar a few months ago and I was experiencing rapid cycling/mixed states when I was diagnosed...at least in my opinion. For example, I would be extremely manic or happy in the morning and become severely depressed at night when the sun goes down. Or, it would do the opposite depressed in the morning and manic at night. It was really hard and I asked the doctor if it was normal for me to switch moods so often even in the same day, and he said it is a normal part of being bipolar. From my own research, I can tell that I was experiencing mixed states. Are you on medicine now, or have you been taking any to help? My Lamictal has helped me a whole lot and I feel like a completely different person because I am now in control of my moods and emotions and I decide when I am happy or sad. The best advice I can give you other then finding the right medicine, is to remember when you are going through these mood swings that it is not your fault. I know you may feel crazy and confused, and really doubt yourself...but remember it is not your fault and the moods will change once you find the right medicine. Good luck and keep us posted about any good changes or changes at all.
