Is it true that "Life Sucks and Then You Die?"?

This has been the weekend from Hell. People who I deeply thought I could trust are showing other sides to themselves, which makes me wonder how naive I may actually be. My nature is to be honest and to trust what other people tell me. Perhaps unconditional acceptance is not a good policy. I am getting some very mixed signals and, once again, as the saying goes, "The best laid plans of mice and men.....". I am now wondering if life is just a serious of problems and disappointments and then you just get 'offed'. Any ideas??
