Suspecting Cyclothymia

I'm gonna preface this by saying I am autistic, and most likely auDHD with plausible OCD and I've heard that ADHD burnout cycles can be similar to the symptoms of cyclothymia, so I'm doing a lot of research and planning to talk to my counselor about it once I'm able to. I have a close friend with bipolar type 2 whose whole family also has some form of it, and we've talked a lot in depth about both of our experiences and how similar they are to each other despite being on completely different levels and timers.

I came here just to ask anyone who can/wants to answer, how would these disorders interact with each other? If anyone has any of the same comorbidities I'm hoping to learn more about how you experience your symptoms together and maybe if anyone has any tips about how to bring it up to my counselor, please let me know. She said she wanted to focus on my autism and getting the symptoms of that handled but I'm struggling a lot right now and I think I just need more help with other things or to figure my shit out.

If anyone could describe it from a more first person point of view, since symptoms are so simplified in most things I read, that would also be really cool. Sorry if there are any typos or anything I say doesn't make sense, I've been somewhat scattered recently if not for all time before that lol.
