You drag yourself out of bed, because unfortunately you have to work to keep your house and pay the bills, so you take a shower (if you’re lucky, you can manage this), get dressed and make your way downstairs. All of this was hard because it felt like you were moving a dead weight. A body that didn’t want to do any of those things. Putting on your trousers left you breathless and getting in the shower almost made you collapse. You likely also felt a bit dizzy, lightheaded or weak whilst doing these things as well, but you’ve learned to manage them, with enough time and persistence.
As you make your way out of the house, your legs are making their best effort to stop you. Walking to work/your car/the bus stop is draining every ounce of energy you do happen to have left after that shambles of a night’s sleep. You feel sick, your heart is pounding and you’re having hot flushes.
