I have display rather strange behaviour once every few months. I think other people go through the same things, but it is useful to be aware of it. I seem to work on a cycle of once every few months going into a deep spot lasting a few days, where I am terribly anxious, a touch paranoid about things, unable to plan and very sensitive about my friends out here. I also become withdrawn and tend not to communicate these feelings back home to HQ. The result of lots of tensions building up, concerns about work, feeling a long way away from home, friends and family, and generally a little out of control – it is rather unpleasant. But it does pass. And for reference, I wanted to put this down so I can see it next time!
