A lot of people suggesting Bi-polar, but to offer a different opinion, ADHD could also fit. Emotional disregulation is often overlooked as a symptom in ADHD, especially in women.

I could suggest this video as a jumping off point for further investigation.

I will also share my experience, because female hormones are really wild, and I think sharing can help others recognize what is “normal” and what can be done. I would say that you’ve given a description which I could apply to myself. I am neither bi-polar nor ADHD. Occasionally I will be having a standard to good week, and without any clear trigger, I will be extremely depressed and emotional. I will, without fail, start my period 2-3 days later. I can also, somewhat reliably trigger panic attacks by drinking to the point that I would call “buzzed” in the 2-3 days before my period. Fortunately or unfortunately, effects of the menstrual cycle can change as you age. These predictable “lows” that I experience only started when I was around 25.

TL;DR You should also talk to your ob/gyn, and an endocrinologist, in addition to a psychiatrist.
