Undiagnosed suspecting possible hypomania- should I try skipping my stimulants?

For years ive suspected I might be on the bipolar spectrum. I have ADHD and every single year in the fall I get these extremely deep depressions

And in most summers, to varying degrees, I have phases of intense productivity, and just extreme intensity in general where I have an extremely hard time sleeping, cannot seem o make myself go to bed nor stay in bed in the morning

I suspect I might be going into that exact stage right now. I’m having a really hard time sleeping. It is 3:30.

It seems taking a sudden emergency dose week long steroid cure for my asthma may also be increasing this I suspect

I want to get a good nights sleep. Or, I want to feel tired and relaxed

Normally when I skip vyvanse it lets me sleep for something like 12 hours, with multiple naps durng the day

Could it be an option to try that? And if I, rather than the normal stimulant withdrawal sleep I instead don’t feel tired even though the withdrawal is physiologically super intense, then I maybe seek some sort of psychiatric treatment?

My doctor retired and they don’t have a replacement until September so currently it’s digital 5-10 mins with GP or full blown psych hospital and they only take the most extreme cases which I absolutely am not
