Doctors appointment tomorrow to discuss symptoms

Hi guys, I've finally booked an appointment to discuss my symptoms with the doctor. I've asked for a blood test to check my hormone levels too. I live in the UK so if anyone here has experience with this advice would be nice x

I don't know exactly how to explain what I'm looking for or what I should do. I experience dizziness and headaches when I'm luteal but I'm worried they'll say fatigue is just pms.

I also fully crashed out last night and had a panic attack and completely lost control, breaking things, shouting, uncontrollable crying, cut myself. I don't know if I should mention this?

I've heard that a lot of doctors here aren't even aware of pmdd which is worrisome tbh and I don't want it to be brushed aside as I'm not very confrontational lol

Does anyone had advice on how to go about it?
