Do not be afraid of anger, rage. It will help you to survive. It can be destructive if not focussed but it does have certain good uses I find.
When you are alone, feeling abandoned, you can go only two ways, up or down. You can decide to survive and thrive or lay down and give up.
It is spring, have heart and decide to live again. You have it in you to start again and make a new path which is just yours.
