You can be cross. You can be as angry as you like but it doesn't change things in any way. All anger does is serve to fuel the bitter, raging, hating creature that is eating you up from the inside out, and by fueling it you are allowing it to eventually become you.

If you are not careful, very soon all that you will be is the bitter raging hating version of yourself, and the other bit, the bit that people once loved will be permanently, irretrievably gone.
