I am a grade 1, stage 4 and know exactly how you both feel. It’s the hardest thing not having answers. I will be having tests in April to see if the prrt treatments have helped. Until then there is a lot of anxiety about the answers. I chose to find activity that gives me creative ways to improve myself and that has helped me with any depression. When I have a bad day I take time alone to give myself space and rest. I live moment by moment trying to be grateful for all I have in my life. It helps me stay rooted and positive.
