Sounds like you are experiencing an imbalance in your hormones. The symptoms you are describing are are not what I have ever heard as PMDD. PMDD is a life long illness that effects women each month just for a week or so.
A friend of mine was diagnosed with Bi-Polar Disorder by her doc who sent her to a psychiatrist to get on meds. She eventually divorced her husband and once she married a different guy, better job, better insurance, and she got a different doc. That doc took her off all the psychiatric meds and put her on some hormone therapy.
The main thing she told the doc that told him right away that she did not have Bi-Polar was that before the psychiatric meds she had only been crazy 1 to 1 1/2 weeks out of the month. The rest of the time she was a good mom, calm, loving, peaceful, never raised her voice, happy, just normal. He looked at her and told her she was not crazy and he knew what was wrong with her.
She was a different person. She has to take her meds for years to come to help her with PMDD. I have seen this woman toss a bunk bed across the room because the sheet popped off the corner as she was trying to make the bed, I have seen her wipe a desktop completely off, computer and all, just because the page was taking to long to load, I have seen her sit and cry for hours because the commercial was sad...it was a puppy running and playing with a child. I had distanced myself from her just to stay safe. Once she started in with this other doc she has been the normal friend I once knew. She moved away years ago but I still keep in contact through FB and she is still normal. She takes her hormone meds every day as prescribed and she is good.
Since this has come on recently I think that is it not PMDD that would have been there all along, but probably you are having some hormone issues that a doc does need to address. I would see another doc and see what they say.
