My dad is caring for my mother with dementia (she also suffers from depression an borderline personality). He is so stressed and keeps saying he needs time away from her so my brother and I hired home health. We are paying for but he complains the helper isn't worth the money (we feel it is), mom goes to adult day care Monday-friday and he complains about the cost of that. We can see his health declining but he refuses to admit it's stress and wont see a doctor. He's even stopped taking his blood pressure meds without an explanation. My mother has always been difficult to live with but my dad hasn't been like this. This is all making me so stressed and depressed. I just don't know what to do anymore. I'm heartbroken that my dad won't let us help and we are forced to watch this whole mess kill him. Is there anything we can do to make the situation better?
