@officeFairy, Welcome. You are going to like this place. It is full of great people, who really love plants, and want to help and to share their wisdom. There is not a cranky one in the whole bunch. I hope you enjoy it.
I am dealing with the exact same problem. Oh it's so frustrating. I got a sick plant, and it was only getting worse. My brain went on vacation and the mother in me went into overdrive, hovering and fussing too much.
Seeing a plant suffering because of root damage is sort of like dealing with the flu. Patience is best. There is not much you can do but let it run it's course, and resist the urge to nurse it back to health too aggressively. It is easier said than done, but it is the best plan of action.
Welcome. Let us know how it goes.
