I have been suffering with very bad PMS for about 6m. It has got worse since dd2 was born 2 years ago, but markedly worse in the last few months.
The symptoms are getting unbearable and I don't feel in control of myself around this time. I am tearful and extremely tetchy and anger quickly. Everything is an issue. I feel depressed, angry and useless for a good week before my period is due. I doubt whether I am a good mother to my 2 daughters at this time.
I also get forgetful and vague. For example, I thought I had turned the oven on, but when I went to check it had only been the grill. I thought I'd turned the dial onto the oven, but dh discovered 45 minutes later that I'd actually turned it off 
It's horrendous. It gets better after my heaviest flow is over (day 2), but I can't live like this for much longer.
If I went to see the GP, what might they be able to prescribe? What natural remedies could I take; in what doses?
I'd really appreciate some advice.
