I've changed my name because this is pathetic and embarrassing. I won't bore you with what is stressful about my life, but it is stressful. Occasionally, not often (maybe twice a month), when the stress becomes unbearable I end up totally involuntarily hitting my head with the palm of my hand. It's because I'm determined not to take my stress out on my children, so I take it out on myself, but since they do see it sometimes I guess this is just as damaging.
I achingly want to stop and manage my stress by other means, but it's totally involuntary at a certain level of stress. I'm too embarrassed to talk about it to anyone.
