The point of living is to be alive. To experience being alive. You can't get the full experience unless you involve yourself fully and live in the life, but the point of the life is not the things that vex you, it's the experience of them. you, yourself, are an entity beyond this lifetime and these experiences, your job is to dive into the life and live it. We get full of expectation and taking things for granted. We load ourselves with the burden of directing our lives so that when something outside our direction or desiring happens we feel cheated.
Yet when something like this happens it's usually something we could never have orchestrated deliberately and yet which gives us an experience so deep and unique and poignant that we are gifted ultimately with a depth of feeling and learning that we hadn't had since childhood. You have the opportunity to learn a whole new life suddenly. Something happens to catastrophically change your world. It's upsetting, it's shattering, it's overwhelming, but it persists. As you persist as well eventually you overcome the challenge and learn to work around it or over it or with it instead of against it. Or all of that, and still resisting it as well.
Whether it's a sudden illness or disability or the total loss of your home to catastrophe, or the loss of your loved ones, it's a hardness humans have faced forever to some degree and it's made us so strong that we dominate our entire planet and even venture into it's satellites and neighbor planets with our machines.
Nobody but a balanced and loving power who wants us to be ground to a sparkle like fine diamonds would ever put us through these tragedies, so that is what happens, outside of your plans, within a greater plan for your spirit, to shine it and give it strength.
However you see the metaphysical world, whether by higher power or personal power, most people acknowledge the idea of the part of them they call "I" is enduring beyond the physical state. That part of us is what grows, learns, becomes wiser and gentler and more loving with the lessons we learn. With strength comes grace.
