I would say i work similarily to Victoria, when i notice a sudden change in my mood i have to stop myself and ask "what am i feeling exactly? where could this come from?"
For example yesterday was the first day of jury duty. So i waited patiently for something to happen, i waited for some sort of progress, like being called or something. then for some odd reason later that night I got really frustrated annoyed because my hubby insists on eating foods high in saturated fat and refuses to get a physical. Like he's waiting for something to go wrong because that's the only time he goes to the doctor and I want to prevent the bad stuff from even happening. I was fine all day but my lack of patience, and frustration of waiting for someone to call like the 100+ people in the room came to head in that 1 moment. Plus my hubby was frustrated that i essentially sit and wait all day as opposed to being productive.
But when i pulled away and asked myself 'what am i feeling and why' savey the people at the jurors lounge bored and 'waiting'. I took a bit much home with me apparently lol
I'm on day two now and today I decided to pack a lunch and then take a walk in the park to ground this energy out as opposed to coming back during my lunch break and absorbing any more energy. I'll probably do the same when the day is over.

don't know if that helps, but i wanted to add my experience to the thread
