You don’t have to feel disappointed with yourself for not being able to alleviate the suffering of others. There are some things that are just beyond us. But what lies within our reach is to empathize, to love, to try very hard to be a good companion, a good listener and above all a good human being. That’s what we can do and that is what we must do. Sincerely love those who need us and show genuine care to them. Commit yourself a hundred percent to your relationship- give it all that you have. If you can do this you have done enough and that should give you a sense of satisfaction.
