What you are describing has some rather unusual happenings. You describe
ultradian behavior (or rapid mood swings) and then shift to a much longer period
between episodes which is reminiscent more of bipolar II. Paranoia is a different illness.

Hypomanic states are stronger than a little euphoria, but they do not contain the
delusions or loss of reasoning capacity in full-blown manic states.

I really don't know what to say about your episodes, frankly, but I wish you well
and hope you find real stability.
