Have you ever experienced a mixed episode?

I'm in a mixed episode and I'm going crazy, does this ever end?
Long story short, it's been like 11 months since the last time I was stable (and in the 2+ years since my diagnosis those lovely four weeks in 2024 were the only time I've been stable.) Ever since July 2022 I've cycled between depression and hypomania, with the hypomania lasting very little and the depression bouts going on and on and ooon. But now my psychiatrist says I'm in a mixed episode and I'm cycling between hypo and depression daily. It feels like I'm going crazy and I just wanted to know if anyone here has had any experience with it and what it's been like, also what was it like to come out of it?
I'm worried about how this could affect my brain, my ability to focus and my nervous system.
