There's no "should" or "should not" when it comes to having feelings. They're part of who we are and their origins are beyond our control. When we can believe that, we may find it easier to make constructive choices about what to do with those feelings.
Fred RogersThe purpose of life is to listen - to yourself, to your neighbor, to your world and to God and, when the time comes, to respond in as helpful a way as you can find ... from within and without.
