She retired from her 30 year job 4 years ago and did not prepare for her retirement in terms of other activities she was going to do to take up her time/day. She has been married to my stepdad for 30yrs and he is 16yrs her junior and still works. My mom is obsessed with her bowel movements and eating foods to help her have them. She is ritualistic in her food consumption to the point of it inflicting with family outings, vacations, visits, etc. She cannot really leave her house anymore for a period of a couple hours or more. If her eating ritual is off track she has a complete mental breakdown. Also, a serious concern I have is the toilet in "her bathroom" is disgusting. Because she eats such roughage, oatmeal, salads, prune juice, etc. she is constantly having bowel movements and it's mostly diarrhea. She does not clean her own self properly and her toilet is a mess of which she has no issue with. It's to the point now that no one can go into 'her bathroom' and she even has soiled robes that she will sit in and not clean. I find this to be very abnormal behavior and am quite concerned about her mental state. I've asked her several times why she is so obsessed with bowel movements and she finally yelled out to me "because they make me feel good!". My little brother and wife live in the same town as she and my stepdad and the rest of her children (my 2 older brothers and myself) live 200+ miles away. She continues to isolate herself to her bedroom, bathroom and her kitchen. Her entire world now is watching the Gameshow network in her bedroom, eating and defecating. Her ability to carry on conversations has also diminished in the last year - although she has never been a social person and is very introverted, but one could at least talk to her for a bit. She loved her work and her coworkers and got a lot of 'purpose' out of her job that I to talk to her about this and try to determine other outlets she can find that will help but she says she's retired now and she's not going to work nor volunteer anywhere. Please help. I really don't know what to do. I'm scared for her and feel very bad for my stepdad as well as they pretty much have no relationship anymore.
