It's going to be too easy for me to say 'take one step at a time' because I totally understand your feeling of being overwhelmed as it permeates every facet of my life right now, as it is yours. It's hard to relax and enjoy life. I feel your pain. I don't really have any solutions to offer you as I'm struggling to find some for myself. Just know that I, and many others, feel your pain and wish you the best. We all need to stay positive for each other.
