Hi @Murray,
Caring for an adult child with a mentail illness is not easy. It can feel like a roller coaster, often with more lows than highs.
Offloading, and getting things off your chest can help a bit. Sounds like you're carrying such a heavy load, I hope that unloading on here helps.
There's a few people on here that share similar concerns who have just posted recently. @JAC has written here about caring for their daughter who has BPD. @karen1 talks about the daily struggles of caring for her daughter here, and @KS1972 is also a mother caring for several children while also caring for an adult daughter with MI, which she has written about here. Also @Frustrateddad might be able to comment here.
@Murray how long have things been like this? Do you have any supports (e.g., family and friends) that can help out?
Hope to hear from you soon.
