Ten years ago, being the single person, I began getting closer to my parents, helping them sell their house, move to independent (dad) / Alzheimer's (mom) living and now am responsible for all things financial and medical. It is their money and they are well taken care of, but my father leans on me (only me) to take care of all of his needs - and continually talks down to me telling me how to do things. I am a very smart and capable person and recently had enough and yelled at him to stop it!!! I then laid into my sisters for going on about their lives while I am my dad's go to person if he needs anything or he doesn't like the caregivers he is sent by the care center, as an example. What do I do not to go crazy and release my anger and resentment?
