I can be bordering on psychotic before my period. Completely irrational, extremely irritable, paranoia, picking fights with anyone around me, terrible rages. I get fixated on trivial things. I then keep pushing people verbally until they lose their temper. Then I go bananas, sometimes end up throwing things, lots of shouting and then tears. It is truly awful.
I have lost relationships and jobs because of losing my temper. I am a single mother and part of the reason the relationship with the father broke up was because the hormones in early pregnancy meant that I effectively had PMT for about 3 months. Not that I was completely aware of it at the time or that my dd's father understood. Appalling.
It has got worse as I got older. I started to realise several years ago that people were telling me there was something wrong and even they knew it was PMT, before I did. I used to deny it. I was fine at other times, just not the 3 to 5 days before my period.
I wish I had recognised what was happening earlier and got some help. I am on anti-depressants right now and these do help. I also take Agnus Castus, which balances your hormones, and Motherwort, Omega3 and 6 oils (including Starflower and Evening Primorse oils) and B vitamins. It is also important to balance your blood sugar, eat little and often and mixtures of protein and carbs. I don't get physical symptoms just mainly the emotional ones. Understanding what is happening does also help most of the time to make me put things in perspective. I still have difficulties, am irritable, at that time of the month but nothing like as bad as in the past.
