Sorry if this is the wrong place but I didn't know where else to put it

So my mum has a few issues (I still live at home), these are described better in my other post but in summary she has a stimulant laxative problem (takes far too many every day) and an alcohol problem (drinks at least a bottle of wine every night, can't give up).

She won't even talk about any of this and just changes the subject. My dad knows and we've discussed it in the past and he just says there's nothing we can do (which is true) so he won't talk about it either.I'm not close to my family.

And I just cant stop thinking about it. About what might happen in the future - which does make me feel a bit selfish actually - and just her issues really. But I just can't get her issues out of my head, which I know sounds ridiculous!

Please, does anyone have any advice?

Thank you
