When I was separating it was a hugely stressful time. I suffered with anxiety and phobias and, for a short time, paranoia. This meant I wouldn't drink any tea that my soon-to-be XH made for me. Seems ridiculous looking back but at the time it felt like a very real threat. I mentioned it to a friend and she thought it was really odd behaviour and judged me for it.
But I think people do weird stuff when they're stressed like that.
