I have been dealing with this for several years. What helps me the most is finding a project to give back with no expectations. Saving the books they are disappearing is one such project (I have a few). If you are a people person, maybe volunteering with the elderly or reading to someone in a LTC facility or walking dogs at the shelter, something that will redirect your focus to an activity where you can make a difference that impacts the quality of life for someone or an animal and you can start to build back your reserves. Others have mentioned how the enemy tries to wear you down rather than open combat; I think this is true and why we have to serve sometimes in areas where we are left alone so to speak. Many service activities have politics involved with the people running the ship; just avoid that part. I focus on the one person or animal that I can make a difference to.
