Oh yeah. Anxiety can do a number on you in 50 different ways: fatigue, inability to think clearly, inability to focus or enjoy things, heart palpitations, sweating, disturbing or repetitive thoughts, insomnia, irritability, sensitivity to noise, and of course just good old pain. Probably many other things. The stuff that people suggested on your other posting should all be helpful: meditation, mindfulness, watching movies or videos that are funny or you like, anything that can take you out of your own mind and you are focused on and/or enjoy, or requires physical effort. For me, serious exercise where I am working hard helps.
