Yep, it was just the one - it scared the shit out of me. I remember sitting down in stunned silence for half an hour afterwards before calling my Mum trying to explain what had happened. I'm pretty sure it was a freak side-effect to my migraines (mine are caused by a problem in the pituitary gland, and are similar to siezures and I used to have to take epilepsy pills for them).

And I don't think anyone really has it easy in relationships, no matter how happy they seem. If the fighting still allows you to work things out and feel happy and loved it can't be too bad. Life's never so pleasant anyway.
