Hypomania?

25f if that matters. My new therapist thinks I have shizo affective bipolar and im just trying to make sense of it. Im wondering if this is hypomania? Going into what I guess is a crash? I've been calling them "lows" since before i knew anything about bipolar. Anyways the last id say 3 weeks ive been having severe, obsessive, destructive thoughts. Sexual thoughts about my mil. To the point where it was debilitating I know its wrong and unhealthy and I just wanted it to stop. When I say it was obsessive I mean it consumed me. I am over it but I almost immediately started getting the headaches and the low depressive thoughts, mild hallucinations. Its been a week and im in the thick of a low. Is any part of this seeming to be consistent with what my therapist is speaking of? I'm just looking for clarity.
