He is almost 75 y.o. he undoubtedly has some mental problems (prior to my mom dying she said he was extremely bipolar but wouldn't take the meds) and had a severe head injury from 40 years ago. He berates me all day and occasionally in public in front of strangers all while living with me. I lived my childhood through early 20's to make him happy and I am pretty sure he hates me now but I don't know if I can stomach putting him in an assisted living. He also is a pathological liar with no grip on reality. I registered and am asking this because he has started threatening me with absurd lies. I do everything for him, cook, take him to appointments, pharmacy 4 times a month, grocery store all the time. I work from home which he doesn't think is actual work because I do it on a computer. I am losing my mind and need some advice. Thank you.
