Just after midnight this morning, I was subjected to a barrage of foul-mouthed abuse from a neighbour's guest when I politely asked them to keep the noise down. Lovely! I went back to bed not feeling emotionally too upset by it (I just thought the guy was a jerk and that I would get advice from friends about what action to take in the morning). However, my body was revved and absolutely would not shut down. It was as though it was flooded with adrenalin but with nothing to clear it away. For the next ten hours, I felt extremely weak, a bit shaky, and had muscle pain that felt like lactic acid. I felt dizzy when I stood up (I normally have OI but not immediately on standing). My heart seemed to be beating faster than normal even while lying down. I kept getting hungry and dehydrated and too hot. My brain also proceeded to go over and over the incident, coming up with paranoid fantasies about what this guy might do, etc. etc. even though I realised this was nuts. I tried to meditate but couldn't concentrate on that, or on the radio, or on reading, or the TV... I must have had about three hours sleep last night. It took about twelve hours for me to become merely exhausted and sleep-deprived and for the other effects to wear off. I've now had helpful advice about the neighbour and am confident I can sort that situation out. However, my questions: 1. Does my body's reaction tell me anything useful/interesting about my ME? E.g. cortisol (which I don't know anything about)? 2. If so, are there treatments I should pursue to address those things? I'm already 2 months into Rich's SMP. 3. If I'm subject to acute stress again, is there anything I can do for immediate relief?
