you are not alone Bookworm, we are all here for each other. I hope your little nephew is on the mend.
I hope your little nephew is on the mend, right now that little one needs the family around. The choice your mum makes is her choice, and she is going to miss out on that wee one! Her loss I say. I know where you are coming from when you say its possibly the thing that makes her stop ( knowing the baby is ill ) We have had many things happen that we hope will be the wake up call but ...no
Just stay strong & look after yourself, I know that when my sisters drinking everything in her life takes a back seat and becomes irrelevant no matter what is happening around her.
Take care of you..
