My step-dad and ex-fiancee really struggle with paranoid schizophrenia (my step-dad ended up on the street in another country with a criminal record before we were able to find him and intervene), and they've both really struggled with being medicated, from pills to injectables. Whatever it is that ails you, I really hope you're doing a lot better these days, and I hope it continues forevermore. I completely empathize with what you wrote, it's very painful to watch someone go through and not be able to help in a meaningful way.

May you be in excellent health, mate, both physically and mentally.
