Welcome, @pattykakes. When will it end is a question that no one can answer, at least not yet. It's a struggle and everyone's road to recovery is slightly different with overlapping similarities. Not what you wanted to hear, I know.

It's early days for you. What I hear over and over again from fellow longhaulers is to be patient and to pace yourself. Perhaps this discussion would be a good place to learn from others who have found deep breathing to way to begin the recovery journey.

Patty, do you notice any pattern to your fatigue or your shaking hands? Do you keep a journal of your symptoms?
