For me, Easter is the day that felt like a crucifixion physically. It was one of the worst physical experiences of my life with extreme heat, chills, nausea, intense pain, pounding heart that felt it would blow out of my chest and so on. Monday wasn't much better yet I was able to sleep through most of it and miraculously wake up for a client and then to facilitate a group. I had tremendous fear about pulling it off yet miraculously felt better for those brief windows. Yesterday was better yet still very painful and I slept much of the day. Today is better still. I am sharing this as many I speak to have experienced similar things and I do not think it is a flu. Hang in there darlings, behind all this shit there has to be a pony!
