Been there and doing that.
I recommend a book titled: 'How to Survive the Loss of a Love by
Melba Colgrove Ph.D, Harold H. Bloomfield M.D. and Peter McWilliams
A quote from the book: "The body, mind and emotions have enormous wisdom. They know how to heal themselves, and the amount of time they will need to do it. Give them what they need to heal. Trust in the process of recovery. You will survive. You will get better. No doubt about it. The healing process has a beginning, a middle and a end. Keep in mind, at the beginning, that there is an end. It's not that far off. You will heal. Nature is on your side and nature is a powerful ally. Tell yourself often, "I am alive. I will survive." You are alive. You will survive". (and I suggest you sing that song alot it's fun! lol). The book is an easy read in an informing an poetic way. By the way I'm here for you as well. GOOD Luck!
p.s. Read in the Bible Ecclesiastes 3:1-8
