Tantrum. An outburst
Responding to overwhelm.
Times up. Let it go.
I find that sometimes it is healthy to “have a fit and fall in it”. Really feeling your emotions and expressing what is going on. A strategy I have used with myself and others, (and this is not original to me) is to set a timer, for say, 10 minutes. During that 10 minutes, yell, scream, complain, kick, punch, move, do what you need to do. Obviously, a little care as to timing and setting is a good thing.
When times up, stop, take a deep breath, exhale, and shake off the remains of your tantrum. Have a good drink of water and back into your regularly scheduled programming.
