Sadness and or grief whether it's about being sick or something else that life has thrown us is nothing to feel guilty about in my humble opinion. There is a fair amount of "toxic positivity" in our world that really is toxic! There is this sense that you have to consider what you have to be thankful for, but at the end of the day sometimes you just come up empty And that's OK! Life is not a bowl of strawberries, sometimes it's a bowl of pits!! We all need to feel safe in wrapping ourselves up in a robe of sadness, it's actually healthy and you have to deal with that sadness before you can really get through it all. It's OK to cry and be sad and ask why me, it's not OK to feel guilty about it, at least to me it isn't.
