Losing my hair at 25, I don't believe my diagnosis is correct!!!

I am having diffuse hair loss, it started in the middle and now is all over. It begun about 3-4 years ago, very slowly, during this time my childhood friend was murdered. I suffered from extreme anxiety, gained weight (8 stone to 10 stone pretty quickly). The hair loss comes and goes at different times of the month.

It's accompanied with itching, hair breakage, I have excess hair on my chin, hands, stomach- get the picture? I have lost weight, still have excessive hair loss. I have been cleared of PCOS, I'm not on any BC never have been.

Dermatologist said I am suffering from androgentic alopecia because my hair follicules have shrunk. No one on either side of my family suffer hair loss.. She looked at my hair for 1-2 minutes then recommended rogaine for men even though I'm trying to have a baby.

What do you guys recommend or think or her diagnosis?
