Can you notice how when you are in a bad mood your relationship suffers? This pretty much happens to all of us. I know it happens to me, plenty. I will feel depressed, or anxious or worried about something and then I am in some kind of mood and then no one feels good around me.
I also know that if I am in such a mood, I am usually unaware that I am in a mood in that moment. After the mood passes I can look back and see how my upset feelings really impacted the way I acted. This is good to do, notice yourself after you have had an upset.
