There is a difference between being unable to get moving and being truly, literally, unable to get moving.
The former is when you are still feeling like you could use an extra hour of sleep, the air outside of your blankets is chilly and uninviting, and you just can't find the motivation to get out of bed. You know that you have to get to work or get to an appointment, but you just don't want to leave your bed. So you roll over, sluggishly crawl out of bed, turn on all of the lights and make yourself some tea or coffee and spend the next twenty minutes in a hot shower that you don't really want to leave either. But you eventually get moving. You eventually, though reluctantly, have breakfast and get dressed and once you're dressed and the caffeine has kicked in, you are wide awake and ready to take on the day.
Today I experienced the latter. Three alarms went off before I even woke up. I woke up frozen. The air outside of my blankets was absolutely freezing cold and I couldn't bring myself to get out. But more than that, my body was shaking so violently that I could barely take my morning pills. I stayed in bed until my meds kicked in and then did what I could to get up. I rolled over, turned on all of the lights, and shakily made my way to the washroom. My tremors were so bad I couldn't do my makeup. I was so dizzy and so lightheaded I kept running into doors and walls. I had so little energy that I couldn't even stand to put my contacts in. I tried to increase my energy. I tried to eat. But nothing was working. My body wouldn't cooperate for anything. I could not physically get in a state to drive, so I cancelled one of my appointments and went back to bed.
When I woke up, I wasn't tired anymore, but my muscles and joints still wouldn't cooperate. I was awake but the tremors were even worse and I didn't even have enough energy to eat. I had to stay seated getting ready and my hands shook so much I couldn't even update my medical journal with how awful I was feeling.
I have no idea what caused it. It could be severe dehydration. I even checked to make sure I have been taking the proper thyroid medication.
There is nothing I can do to change it. I just need to grin and bear it. Or go to Emergency to get some fluids - which is an entire process I'm not sure I could handle right now.
So I sit and wait for my energy to improve. I drink fluids and eat salty food to retain some water. And I hope with all that I have that it was a one-day relapse... cuz doing that every day again for another few months isn't something I can take right now.
Fingers crossed.
