@Bea No we cant change our family, but we can only do what we can do.
Love your humour about brown bear probs. In a way I was lucky my mother was proud and organised her own palliative care, which was appropriate. So I never had to do that job for her, but she was a bit insulting and abusive and neglectful to me. She did not want to trust me. I witnessed clean ups on visits and was thankful to workers and kind to mother. My mother had a diagnosis of SZ at once stage.
Schizophrenia is a serious and often scary disorder and word and concept for family members to manage. I was told at 18 that my dad had it by my brother, then went to check at dads old hospital. I married a fellow with it. Many people say they over diagnose it ...
The down side of the break up of extended family is the increase in pressure on nuclear family.
I also took on the baby of what I call a "happy schizophrenic" ... maybe you can get my irony ... she was a person who ditched all responsibilities ... but was fond of fancy clothes ... for herself and her bub ... while my babes had to take their BS. At least the man I was married to for 16 years tried to face up to life. I distinguish happy irresponsible Scizohprenics from others and my own parents who actually had a lot of real trauma, skills, courage and sense of family duty as well as that diagnosis. Not all Schizophrenics are equal.
Do what you feel and think is right.
Cant do more.
