Good luck to you in whatever new life you and your children find. I admire your courage to seek such a dramatic change and am confident that you'll be rewarded. I am also confident that wherever you land, it won't take long until you discover at least one major reason as to why you are now living in your changed situation. After the test, comes the rewards.
Wrestling with a traumatic brain injury for now over 30 years, I have experienced a litany of neurological symptoms. The last 4 years have been particularly difficult as I have been forced to take disability from a very successful and beloved profession due to frequent incapacitating migraines (currently 80% of my life). By far, the greatest medicine, strength, comfort, and optimism come when I focus on others and their needs. When I lose myself in the lives of others, I truly find myself and vice versa.
It is a fundamental Christian doctrine and I am a devout Latter-day Saint (Mormon). Obviously, I daily fall short in this regard, but I regularly have the opportunity to serve and care more about others and their trials as I am a husband to a very strong wife and father of 7 remarkable kids, all at different stages in life. Also, as part of my Faith, I have been blessed to be assigned as a "home teacher" to an elderly widow. This is a primary way the Lord takes care of His children, via others. Whenever I am able to visit her and provide even the little service that my health allows, I am reinvigorated. It is nothing short of miraculous. Like the "camel and the fish" analogy, this principle is much more easier said than done. Yet, it is a true principle and I hope and pray that I will have a greater desire and disposition to put it in much greater practice. My head pain remains, but my capacity to endure it increases immeasurably, not to mention forcing my selfishness away from my own tribulations.
