There now follows a link to storify, as I have already told this tale on twitter. And can't be arsed typing it all out again. And I'm not embedding storify on here because it looks AWFUL and takes ages to scroll past for those who have already watched it unfold on twitter.
Basically what it boils down to is this: if I get mega-stressed and I can't utilise either of my usual coping mechanisms* my intercostal muscles will pull so tight that they will tear my ribcage away from my sternum. I do not see the evolutionary advantage in this capability of the human body, but apparently it's pretty common.
So I have to take a couple of days off work (which work have been very gracious about) and avoid stress. Trying to avoid stress is going to be very stressful, I think... -_-" For one thing, how do I stop the nightmares? Any tips gratefully recieved.
In slightly cheerier news, I got the results back from being a responsible poly person and going to get tested today, cos I know you're all waiting with bated breath for this. As expected, I am all clear on all tests.
*one of which is admittedly healthier than the other. Neither of which are available to me at work.
