Fortunately L.O., this is not true. While it is terribly sad that you were unable to save the ones that you loved, you are still capable of doing much to help to "save" others. The opportunities are everywhere. You have to WANT to help others...others that you probably don't even know and may not care about. You are still able to let yourself care, which of course will mean that you may very likely "get hurt again"...that is the price of loving, the price of caring once again. I can see a good deal of what we call "character" underneath all of your sadness. It is commendable to "keep on keepin' on" for others, when your heart is not in it. That is an heroic characteristic, and I expect that it will serve you well...in the long run. Miracles happen...but they don't JUST happen. Somewhere along the way someone MAKES them happen. What you have lost will never "be restored" to you, because what you have lost is irreplaceable, is it not?You can't recreate the past, but you can craft a future that is worth living...it requires "letting go" of the past. That "tenuous hold on the world" is your lifeline. You have to USE it to create a new "life worth living", and not knowing you, I have no idea what that will be...and most likely you don't have a clue either. Perhaps if you delve deeply into your past to recall "what sort of stuff used to make you happy", that will give you a clue. But, in any event, you have to work at forging a new purpose for living...living "for those that depend upon you" won't work forever. And besides, you really will be much happier living "for your own purpose" I wish you joy.
