I have been diagnosed with PMDD. It took a super episode for it to be diagnosed (I was out of my mind not being able to slow down my thoughts and/or emotions.) I have a BA in psychology so I knew the thoughts/emotions were not real and I could rationalize things to myself as I tried to get help. I told my PCP (because my health insurance did not cover any psychiatrists in the area), and I told him I can feel my period coming, not in my body, but in my head three to four days before it starts. I also have such a hormal flux, that often I feel like I am going to throw up those days. I went through the gammit of anti-depressants (Proazac - made it impossible to reach ... um ... well the big "o", Paxil wore off, and the other SSRI's (selective seretonin reuptake inhibitors), and ended up with amytriptiline and that one seems to help most. My doctor also prescribed Ambien (because it often causes me insomnia) and clonapin for the times that my mind will not slow down. For all those who doubt the exsistance of PMDD, I say that if a man felt the way I did that day I was frantic to find help, then we would have a definite treatment and cause for the disorder.
It is a rough road about once a quarter, but the therapies seem to help the rest of the months.
If I were her, and she trusts her ob/gyn send her there. If she likes her pcp better, send her there.
I also suggest that she look for therapy as well, because it sounds like she has some issues that are exasperated by her hormones.
I hate who I am during that 4-5 day period, so that's why I got help.
