it is very sad to hear that. I had a very same experience many years ago, a person I did not know very well asked for help for a second time and I refused because he had not pay back his debt to me yet. After a few weeks, I heard he killed himself. I was so mad at myself to be so cruel. I did not know he really needed help that badly.After this event, I told myself if it is possible, never say no. Losing a life will never come back.
It is good to hear that you have such good heart. You will get get you reward. You are sweet.
