It's been three plus years of solo caretaking in my home. Dementia seems to have caused his self absorbed behavior to explode. He is pacemaker and pill dependent. Even though he reminds me how I am a liar and try to make him think he's crazy/nuts (those are his words,) I feel guilt. My sister is having a family meeting this weekend to bring it to the table, at my house, so that dad "sees how much WE are doing for him, how much WE care." My brothers are absentee, not even a phone call unless they need something! So, I resent those words that were used, because they have done NOTHING. Honestly, I have told my husband that my dad is going to blame me for "throwing him out," and will think I cooked this up all by myself. This will be a nerve wracker of a week. I'm sorry, I needed to vent.
So push that guilt beside, you are doing what is best for your Dad, and that means a higher level of care by a staff who work 3 separate shifts, not work 168 hours a week like you are doing.
