I used to have a phobia of dogs. It was to the point where I once reflexively ran into a road while cars were moving to avoid a small, harmless looking dog that was on a leash. My body eventually ran out of energy to keep producing that fear response, so now my chest just feels slightly heavy around dogs.
Sharp objects being near me in certain situations. One time someone kept trying to poke me with a pen and my fight or flight response activated and I choked him. I'm not sure if I still have the same level of fear for this. I could've ran out of energy for this one too. Every negative/strenuous feeling for me seems to have a finite amount where eventually my body and mind just don't have the energy to produce it anymore. It's not that I get used to the events that cause the feelings, my brain just gets too lazy to feel the feelings because of how much mental energy it uses.
Is there is a synonym for energy? I used it at least 5 times in this post. . x .
