As DJ would say "that was then, this is now".Focus not on what you've lost, but what you have gained. Find gratitude in your heart for even the smallest of blessings. Reflect in wonderment on the lessons you learned .When you say you took the wrong turn in life - maybe it appears that way now to you, however, there is something of value you gained from it. It is up to you to acknowledge what that is. If its as much as not making the same turn again, then you are blessed. Start small. Find joy in little things. Breathe. Get out of that house & do something kind for another human - if for no other reason than giving something of yourself, back to life.  Sing very softly.
