My 89-year-old dad has been having frequent fainting or syncope due to end-stage heart disease (aorthic stenosis). In addition to this he has dementia in middle stage. Every time he has a blackout, he scares me to death. I feel like I'm not tolerating well the horror anymore. I feel that the emotional weight of these two diseases for me is too much. I think it's about time to take him to assisted living. We have lived together for almost three years and caring for him has become very draining. I´m an only child and my only support is my husband. At the same time I feel lots of guilt for being so cowardly. Please advice.
