BOTH Bipolar I and II? How?!

I talked to my psychiatrist today and they said that i’m “teeter-tottering” between bipolar 1 and 2 because i have all the usual symptoms of bipolar 2, but me staying up for 48+ hours during my “hypomanic” episodes is not very usual? has anyone been through anything similar? like they said that I lie “somewhere in the middle”?

(my other diagnoses are atypical anorexia, ocd, and autism spectrum disorder)
