walking, or talking to Buster. He can tell the difference between when I'm sad and angry, if I'm angry and upset he generally just leaves me alone, if I'm upset about something making me sad he comes and finds me and licks the tears off my face, sounds corny but he does.
I do tend to write when I'm really upset, but I don't tend to write when I'm happy. I do have a journal, but everything in it is negative because I only use it when I'm in a bad mood.
