Anger is a common response to grief. Particularly since our culture doesn't like grief and there's a lot of societal pressure to "get over it" in a ridiculously short amount of time. Anger is more socially acceptable than prolonged grieving. Anger feels easier to the person grieving than acknowledging their grief does.

Have you tried keeping a journal? It'll get you writing again, and it may help you deal with all the frustrations and grief in your life right now. Seriously, we understand about RL and (especially!) family taking precedence over online stuff.
