I'm terrible, I would cry because I'm so grumpy and don't want to be and can't snap out of it!
Have you tried taking evening primrose oil? The only problem is you have to take it a while for it to work.
Try seeing your doctor they may be able to recommend some type of contraceptive pill to help lessen the symptoms.
Reflexology can help to balance out your emotions and also try looking for an essential oil that is calming and can help you relax.
Try going to the gym and listening to some full-on music and work out until you have no energy left! Exercising may help to lessen the depressed feeling too.
A healthy diet and stopping smoking (if you do) can help.
If you know how you are going to be, try to catch yourself before you get the "rage"/jealousy/paranoia, take deep breaths, go for a walk, a bath or something else you find relaxing and tell yourself its just that time of the month.
Finally if this doesn't work, kick your other half out for a night, drink wine, eat chocolate and laugh and cry at Bridget Jones! Hope you find something that works x
