well it is completely normal being feeling for others and their pains or griefs. But feeling them is one thing and sharing them is other. I feel that too being sad and yeah i feel tears in my eyes too.. but soon i control over it and try to help the poor guy… or if i cannot i ponder over ways so that how could we prevent this , the people from being sad and lonely.. the solution is to feel and help..
I think human means is to feel for others and lets not just carried away with this try to resolve that issue
