Courtney,
Sorry, it has been a rough patch. Stop and take a breath.
Your brain is running in hyperdrive trying assess every possible outcome, while multitasking the appointments and things that need to get done on time. It is doing unnecessary work trying to protect you from imagined horrors.
Time to unplug for a bit. Yes, it is a scary world out there for us, but we have small safe spaces available. It may be as small as your home, or as big as a city, but safe places do exist. Yes, we are attacked as a group, but not as individuals. Those people don't know who you are, and they are not looking for you.
Relax for a bit, take a nap if you can, and focus only on the things that are impacting you directly, like your appointments. As my dad likes to remind me:
90% of the things we worry about never happen.
Go easy on yourself.
