No, you are right, none of this is fair. Unfortunately, like my mother used to say, "Life isn't fair." Loss, tragedy, happiness, luck....it's mostly random. It doesn't even out in the end, and there is nobody to blame for it. It just...well...happens.
It's easy to feel like you are being singled out stuff like this....that the universe, karma, God, or whatever you personally believe "has it out for you" in some way. I've been struggling with this feeling a lot in the last two weeks. If you are religious, it might help to talk with your priest, pastor, or other clergy. If not, and these feelings persist, then it might help to see a counselor. This is my plan...
