I know your pain. Once I got over grieving. I started spending time with the ones I still have. If I were to truly give back. I'd try getting a critical thinking class on every school curriculum in the country. But I don't have that kind of time or resources. I tried "giving back". I found there are very few people on this shithole that deserve my kindness and giving. There so many people that need help and when they get it, all they do is take advantage. Do what you will. There is no reward if the people you help don't appreciate it. You just wind up disappointed and feeling used.
