I can feel you as so many times I also went through this type of situation. Yes, we might not hurt anyone by doing nothing but if we did something for them at that moment, it would be more significant to those persons. But it's not too late yet. You can help others from now which may help you remove those guilty feelings from your mind. All the very best.
Yeah, we always can help but sometimes some things lefts such a hole that is hard to fill by any other means, all we can do is just forget about it and move on. Thank You for stopping by.
