Is there a mental illness for this?

I have no clue if this is the right subreddit for this, but I thought id ask. So basically for the past I dont even know how long, I've been experiencing very frequent (for lack of a better term) mood swings that i can only really describe as (for lack of a better term) manic (I could very well have a flawed understanding of the term manic tho). And it all happens within 1 day. Basically how other people describe it is like panicked or almost insane in a way from the people that have witnessed these episodes, and like I cant really describe it very well becuase i never remeber it correctly. Idk I just kinda go into a spiral. They could last anywhere from 30 minutes to 3 hours (from what i remeber). It could just be hormones but almost everyone who witnessed them seem to say that its way too intense to be hormones. I did some research but I cant find anything that quite describes it, as its all things having to do with bipolar. ​​My psychiatrist said something about dmdd, but I just dont know if thats the case. My mom also said something about it being OCD also. Idk I just dont feel any of these are right but im not an expert.

Im not trying seek attention, I just want to know if theres anything that could possibly be an explanation for this. Im sorry if I came off as so.
