Thank you, Mags, for another fantastic OP.
Many hugs to you, Manta. I am so relieved to hear that things seem okay with your boss. Walking seems a great idea to me. Not only will it tire you but, if you let yourself escape into nature - the air, the rain, the trees, the sky, the sounds, - you can empty your mind and absorb the goodness of life. It can be a freeing experience. Be sure to take some water along with you.
