During my last session with my therapist he mentioned that I may be rapid cycling. I have been having frequent manic and depressive episodes. I estimate, 2 or 3 manic and 3 depressed episodes just from January. I know that alone makes it rapid cycling but this past episode I’ve had this month has been hypomanic but I had 2 very low nights within that span but back to hypomania by the next morning. 

Is it possible to be both? What are the differences?
