My brother (who lives in another country) has 2 teens. The younger (DN, 13yo) / has major problems - severe anxiety, complex mental health issues in the context of neuro diversity (no learning difficulties). Older child is doing fine. DN has not been to school for several years, they have no friends or social contact, and my brother's life is dedicated to caring for his child. He's separated from the child's mum but they co-parent well. His work is massively disrupted (he has understanding employers but he gets little done and is unfulfilled). He has v limited social life and his health is not great (no time to exercise etc). DN will not spend time with anyone other than parents. My brother says they couldn't possibly consider respite or residential care as would be too traumatising for DN. He has not been able to visit family for many years due to this situation. he's on call night and day in case there is some crisis.
The situation all feels so awful, totally stuck and my brother is very low. My thoughts are that unless they do something like residential care, nothing will change for anyone. I also think DN will be highly distressed no matter what, and that it's important to find space for other family members needs. But my brother thinks the distress would be too much for DN and cruel to do this, and obviously he's her parent/knows the situation much better.
Things have been like this for a few years and seems to be getting worse.If I was in this situation I don't think I could be so self sacrificing, but maybe I would feel different if I was in his shoes. What would you do in this situation? Do i encourage my brother to try make some change even if distressing for their child? Is it reasonable for them to sit tight for another few years and hope things improve in adulthood? But if DN cannot regulate emotions at all and isn't engaged in anything that would support this will change really happen?!
