I think that my energy level is supplied in a great abundance so I can continue living, and it's up to me to harness and deploy that energy. Too much of it can overwhelm me, so I can see why I suffer so much.
Another analogy is to a train, so that "Anxiety is like a tunnel, just drive through the tunnel, and you'll come out the other side". This involves trust, so you might have to work with someone to learn this.
The other one is, "anxiety is anticipation holding its breath", and this might be a different way of looking at it. If you like sports, a water analogy like "riding something out" might help you more.
I'm glad you brought this up, since I'm having challenges with mom getting out, and forget my own experience.
I have a course starting tomorrow, and feel wired beyond belief the first day, so I can't sleep. This subsides with time, and I can't afford the sleep disruptions, since I have competing activities which need to get done. Part of me knows to schedule a massage before the class, but I'm such a tightwad on top of being a procrastinator and perfectionist(what a misnomer!).
All that energy hurts my ability to process...life...but I treasure the energy, since some people don't have it, or have less of it.
