I have been managing my mood and emotions most of the week after a trigger event at work. I commend you implementing your go to mood stabilizers!! Keep rocking it Anc. Mind over emotions, even when ours are feeling out of control.
I like the vision of you taming your monster. I wonder what yours looks like, imagine if you could turn it into to Sulley from Monsters Inc, every time it turned up.
