Jack frost knocking at the window pane!

Another sunny, really cold day. Lovely to see the sun. Went out in the garden mid-morning and this blip is my shed window. Took quite a few, fascinating! Also took one of a pansy that was iced, looked as if it should be on a cake!
Still not feeling right but the blood tests showed nothing wrong. Doctor thinks it could be labyrinthitus (?) and just have to give it time!!
