F before the T? PMS/perimenopause

I find that sometimes I wake up in a foul mood, or angry/raging, and it’s definitely hormonal as I’ve tracked it against my cycle. I’ve tried to fit the feelings into the model but they feel more like a circumstance: a biological phenomenon not preceded by thoughts that I can identify. I cannot find thoughts that are leading to the rage, more horrible thoughts that result from the feelings. Is this possible? Shall I treat pms rage as a C?
