But one is a degradation problem.

Tag someone still figuring out which one they have.

She's doing her best. Her best is the problem. 🌿
Tag someone whose nervous system also needs a chill pill it can't take.

The "overprotective bodyguard" is one of the kindest ways to think about a dysregulated nervous system. It isn't broken out of malice — it's stuck in protect-mode, reacting to small things as if they're emergencies.
When you understand that, two things get easier: you stop blaming yourself for "overreacting," and you start responding to your body with patience instead of frustration. You're not dramatic. Your alarm system is just sensitive — and sensitivity can be worked with, gently, over time.

Save this for your next doctor's appointment — and send it to someone whose body hasn't felt the same since COVID. 💌
