You can be intentional about taking good care of yourself, by eating and sleeping well, getting plenty of exercise, and doing things that you enjoy. You can choose to be among people you enjoy and avoid those who do not understand your loss. You can do things for other's and realize that you can still make a difference in others' lives, even if you're missing desperately a Fur Baby you love. Many are the times that people report they have grown stronger as a result of the loss they have experienced. They grow more mature, more understanding of others, more aware of themselves.
Many people learn new lessons about the meaning of life, as well as the meaning of love.
These are often difficult lessons, lessons one wishes one did not have to learn in this way. But they are gateways into a brighter future. It hurts to lose a cherished relationship with another, or a significant part of one's own self. It can hurt to lose that which has united one with the past, or that which has beckoned one into the future. It is painful to feel diminished or abandoned, to be left behind or left alone.
