Breathing exercises like the ones mentioned above help me, and listening to my favorite music, which can range anywhere from very calming to very "angry" lol. Venting helps me too, especially if I'm allowed to cuss, because I have a mouth. :x
One mantra that helps me get through tough situations is reminding myself that if others have been through it, I can get through it. One way or another, I have to push through it. Usually the experience turns out not as bad as I thought I would, so that helps me too. I remind myself that it won't kill me, whatever it is, and that I'll be okay in the end, even if it's not the perfect experience. Helped me get through being in the hospital while having my son. I was eerily calm through it all, and part of me wonders if I was being apathetic or going through some other mental something or other. For reference, I'm just over 100 pounds soaking wet, and my son was born 9 pounds 7 ounces. C-section of course, but yeah, I was surprised how calm I was knowing what was coming.
Goodbye, Voltra.
