The only thing holding me back right now is my dad is seriously ill in the hospital with cogestive heart failure and pneumonia. He has lost most cognitive function and the neurologist wanted to do a lumbar puncture on him today to determine if he has a blockage of cerebral spinal fluid on his brain causing some of his problems.I had to inform the neuro that my dad is on blood thinners and can't have a lumbar puncture untill he is off of them for a while.I am afraid to leave him right now so we are on a wait and see basis.
