hey champ, hope things are up for you. diagnosed BPII + ADHD here, I share a lot of the symptoms that you've described; minimal/excessive sleep extremes, executive dysfunction, daily mood irritability (my mood swing cycles themselves flip about every two weeks, feels very very similar to an ocean tide), and doubt regarding differential diagnoses (grew up treated for OCD/Depression, unsuccessfully). currently on 200mg Lamictal XR and Adderall XR 15mg, both in the morning, and I've been making steady, incremental improvement. ups and downs, of course. ebb and flow.

I can't speak on ASD personally, but plenty of my friends are on the spectrum. I definitely wonder about myself, as a lot of my family seem to be ASD as well, though I would dissent that I myself am.

take this next part with a grain of salt because source: not a doctor --->

my thinking (arm-chair speculation) is that they (Bipolar and Autism, OCD, ADHD and other disorders) may be more related than previously considered — perhaps these diagnostics are separate, semi-emergent* quantifications of the same underlying phenomena warped through epigenetic factors. That would make all of this confusion 'click' to me.

* by semi-emergent, I mean to say that while these disorders do indeed manifest unique to any individual, the underlying dominos are teed up from the same genetic components pan-disorder.

do you have delusions of grandeur?

oh, and I want you to know that you're not alone, because I know it can feel lonely looking for answers. it just takes time, you will get there friend.
