I’m so sorry you’re going through this. It’s so scary, not knowing whether you will stabilise or improve, not knowing how low you can go.
I’ve been sick 20 years and had lots of different baselines. I’ve had crashes for a few months and managed to recover to my long term functionality. I’ve had a very bad year and lost a lot of functionality, markers of my life, and my independence, but I might improve again. I tell myself that things can change. But my goodness the uncertainty is scary.
Sending you a hug.
