Whether you lost your job or someone you love, there is a blessing in disguise waiting for you. First of all, let yourself grieve. Go through what happened, perhaps even summarize it in your journal or make a scrapbook with pictures. But instead of getting stuck in pity, or even denial, you now get an opportunity to transform this loss into something else: Freedom.
What you used to have, you are now free from. Think about it. Which kind of opportunities do this entail? New relationships? New places? New work? Or simply the lifting off a heavy burden you no longer have to carry. You are free! Now, how does this make you feel?
I've practiced this myself, even with the passing of my mother, as well as when I changed career. Always ask for actual examples when you listen to, or read, teachings about healing.
