@Pepper. This is temporary hell. And I know it is, I worked in long-term care a lot of my career and cannot imagine not being able to walk out the door at the day's end. You will heal, but your (highly justified!) emotional distress is impacting your blood sugar and hampering your body's ability to repair itself.
Your environment is
guaranteed to cause stress. This is the time for soothing music, light audio books thorough
noise cancelling headphones or earbuds, things like aromatherapy if you find scents soothing. With a mind as excellent as yours, facility activities like the reading group are just going to cause more stress. Remember, you're not there forever, you're there to heal but the environment is not!!! conducive for doing so. Ask your son for the things to create a cocoon for yourself, a Pepper pampering oasis in the middle of the facility chaos. Sometimes isolation is a good thing.
Wishing so much I could send you things to help with this--a comfy sweater and lap throw that you know was given in love, a refreshing body powder in your favorite scent. But since that's not possible, I send you heartfelt wishes that you'll find the means to retreat from a chaotic enviroment and create a safe space in which to heal. And come here for connection with friends who care.
