80% of the time when I feel this way, it's hormonal -- I wish I could identify what it is the rest of the time. I find it very helpful to be able to say to myself 'this is hormones talking, not reality.' If I can't say that, it sort of digresses into a vicious circle.

The impact hormones have on the way I think and act really creeps me out sometimes. It's bizarre to think that something we really have little control over has such an impact on the way we behave. I try to remember that when I'm reluctant to give someone the benefit of the doubt!
