It's not impossible it is actually rather severe in your case, just from reading your posts, because you might suppress it. So it doesn't happen often, but if it happens it's severe.

You might then be in some constant, mild mixed state (with or maybe only without meds). You might then stop mania, just by relatively quickly surging anxiety, before it can develop into something that becomes worse by anxiety. Panic attacks, the most extreme form of surging anxiety and fear, may even stop mixed state pole switching, stabilising you. However, if your thoughts speed up very quickly, it might be (the start of or very brief) psychosis rather than (just, in some ways) a panic attack, like a very, very short psychotic mania.

Severe mania is more about impression than expression. That makes the BP syndromal description less useful: quite a few symptoms/signs you may not have because you have gone so quickly beyond that stage (due to anxiety and fear) where you might display those symptoms.

Excess energy, lack of appetite and self-transcendence (exactly what you describe) are the only real symptoms that you can probably always rely on to distinguish mania from a normal state.

Risky behaviour is really only "required" to make mild mania more severe. If it's already severe, the risks are high enough or too high (giving feelings of ecstasy or extreme anxiety/fear of losing control, much like a panic attack but with perceptual distortions typical of mania, not (just) dissociation).

I used to think my symptoms weren't severe enough for BP treatment. What I discovered is that it's actually quite/very severe. I also have the schizoaffective disorder diagnosis and probably for that reason.

Meds make me display more BP symptoms because it makes mania less severe and reduces the time I am in a mixed state.
