Yes I understand what you went through. My mind goes blank at times, my brain feels hot in spots. I suffer tension headaches, stress. My mind gets on overload and it just wants to space out. It might be neurological. Definetly have that checked out. Stress will affect you in many ways. Drink a lot of water and take a nap when this happens. Water helps hydrate the brain that is being affected. And do not wait to go to your doctor for more follow up. Blessings...
