Rich, saddened to hear of your loss and can relate to how you feel.
I was married to my first wife for almost 23years before we divorced and then she went back to England and died in 2001, only two years after we split up.
You have to take time for yourself and put "YOU" first, then you will be able to help other people after you are in a better frame of mind.
They say "time heals" but everyone is different and i found that time "softens" the pain from before.
Remember all the times you had with your spouse and treasure them all, (even the tough times) its all relevant to you and grow daily AND reach out to people. Everyone thats been in your situation has their own feelings and deals with them differently but you can gain strength from other peoples experiences.
Keep her in your heart and talk to her, she is still by your side. I wish you all the best in the future, Des.
