That's what we all are doing.
We are waiting for God to say it's our time.
It's what we do with that time which counts.
God welcomes us when he sees fit, as along as your here you have a purpose if you choose to follow his path.
What he has in mind for you I can't say, however, I'm sure it does not include curling up into a ball on the bed.
I don't know how you came to think you hurt some-one, but if as you say you were trying to help, that can happen.
That doesn't mean we should not help others, it's just sometimes no matter your best intentions someone gets hurt. That includes the person trying to help.
Generally this happens when the helping is of a match maker, or manipulative nature.
That is why we learn to stay away from those kinds of situations.
Otherwise helping others is a good thing to do.
Anyway we are here to help, as best we can
