And yet, here you are connecting with both those of us who are responding on this thread, and an unknown number of others who read it.
Remember, we feel as lonely, abandoned and fragile as you may (I'm just guessing here) and have no solution to our own individual problems. If we did we may not be here.
Often our inabilty to find the "correct" words to try to assist or relate are down to how bad we are coping, rather than not relating to your position.
Go well.
