One of the most beautiful and insightful postings I have ever read. Thank you for summing it up so eloquently.
The advice is true. We do come out of this much stronger and more confident. BUT, we have to do the work. The grief is the first thing to deal with. And deal with it we must. However long it takes; however far down it goes. The next stages come, with some overlap in between. When you come out on the other side, you have grown into a much better version of the person you once were. Difficult way to do it, but worth who you find in the end.
Hugs and God bless you along the way. He did me. Mickey
