Have NC for this as don't want to risk outing, for SC's sake.
SC is 16. A few weeks ago they told their dad (my DH) that their mum is drinking. DH knew that his ex drank when they were together, but she left him (taking SC) 14 years ago. Since then he has seen as much of SC as possible so SC has grown up close to both mum and dad. He did not think that his ex still had a problem with alcohol - she managed to hold down a job and bring up a child. SC is a fantastic person, very bright, thoughtful, kind and perceptive. Relations between DH and his ex haven't been great, but I don't know ex at all well and I've tried to keep open minded (and done a lot of deep breaths) since DH and I got together 9 years ago.
So here's the thing - we've known for a while that SC has some problems with anxiety and other MH issues. Recently they thought about coming to live with us (we have 3 kids together) but decided not to in the end. A lot of things have fallen into place now they've finally told us that mum drinks and does the typical alcoholic thing of having a go at her kid when she's drunk, then apologising when she's sober. SC obviously loves mum and some of SC's more strange behaviour makes sense now we know the really upsetting position they are in.
What I don't know is what we can do now? How do you help the child of an alcoholic understand that it's not their fault? I care so much for SC and want to help them grow into an adult who is free to make their own choices and doesn't feel responsible for a mum who is ill in this way. But I've no idea what to do or say.
