Questions about the cyclothymia experience

While I was explaining to my doc about my emotional cycles, he suggested it’s very possible I have cyclothymia.

When I got diagnosed autistic at 19, there remained two big ??? that addressing autism alone never seemed to touch: my inability to focus + my emotional cycles. Recently, I’ve discovered I have ADHD and have been working on treating that, but this still hasn’t really touched the emotional cycle issues, which has been disappointing.

Basically, I cycle between “good” and “bad”. On a good cycle, I feel good, productive, motivated + I want to work on all the projects (the success rate of which varies depending on my ability to concentrate). My self-esteem is better. I want to catch up with my all friends. I’m more active with strangers on social media. It great, honestly, other than, again, my ability to focus isn’t consistently great, and if I’m hyper focused, then it’s difficult to funnel that good energy into stuff that needs to be done. Sometimes I suffer what I call “runaway train” mode where I am going so fast, and I can see I’m going to crash, but I cannot stop it.

And then there are the bad cycles. Usually happen right after a good cycle. The typical depression symptoms. Completely kills my momentum and usually wrecks whatever good habits or systems I had try to build in the good cycle.

I’ve never really found a solid explanation for this. Is this relatable to your experiences with cyclothymia?
