A tad nervous

Today has been lovely, gym this morning, playing with pup in garden then walk in park and coffee with daughter and both dogs. They are starting to get along better.
I have no idea where these stones came from but they arrived a few years ago, I think hubby brought them back from a beach.
They are quite calming and tonight I need calm as I am a bit nervous as having an MRI tomorrow morning. Off up to Northumberland in the afternoon.
