Yes, can definitely relate to the faint. Although Im not so sure it is a true faint. I have gone at least a half dozen times in the past year. Some I felt coming and others there is nothing but someone standing over me when they find me. I wonder how many times I have banged my head and dont know it. As far as people thinking you are exaggerating, I quit caring what anyone thinks awhile back. Those people around you that truly know your difficulties can see you are no longer the person you were before PCS.
