To the OP (and those in similar circumstances) I can only offer my sincerest sympathies and hope for healing to come quickly.
To those of you who have offered your own stories and advice I can only add my own nuggets of so clled wisdom to yours.
We are never granted the foresight to know when our lives will end. All we can do is live each day as if there will be no tomorrow. Obviously that doesn't avoid the fact that we need to be reasonable about what we choose to do, at least financially.
During my working career I had a customer that manufactured caskets. I can assure everyone that they do not build in a secret compartment for us to take any money into the next life, wherever that may be.
We can't allow life's setbacks to dictate our future.
We can't stop living because of our grief or we will leave this earth before we have lived. A broken heart is just as disabling as a terminal illiness if we allow it to rule our daily life.
Although it is often difficult we must get up and go forward every day. Our departed loved ones would want that for us and to honor their memories we are duty bound to do so.
