I find that getting angry helps me do two things. The main thing it does is keep me from melting into a puddle of tears about everything. The other is that it helps me stay strong about keeping my boundaries. But I feel the real satisfaction comes from being, the person I want to be, someone strong enough to be calm and loving when confronted with other people's sickness. Of course, sometimes, it just feels good to get mad and so I give myself permission to do that but with the goal of remembering to be who it is I want to be.
