There are many things that may happen during our lifetime that may impact us personally. We have a choice to park beside pain and loss, or to move on. Some things may be a direct result of our choices, but many times as a result of other's decisions. It can be nearly catastrophic when people who matter to us, don't consider us in their decisions, but it happens, often more than we realize.
When things are evident, and out of your hands, by either choice or circumstance; realize it is part of life, and you can get through it. As a wise person once said, "the sun will continue to rise."
All that comes is life, not necessarily good or bad, just life. It can be a mixed bag, but the good and bad of it is really how we perceive it, and how we respond. Grow, change, embrace good, or sit, sulk, stagnate, it's really up to you.
