Hi Lindyloo,
So sorry to hear your having a bad time, sending you a hug.
My Son used to miss work as well, and it really does start to upset you when this happens.
As you know my son has been to Rehab twice, but I do believe it helps, they are usually run by people who have themselves been in the same situation, I met some great people at the Rehab where my Son was, so warm, welcoming and just really nice people, and some of them had been to hell and back on their own journey.
There is some information on here in the Story section about a lady who opened up a Rehab, it is not too badly priced to be fair, but your Son has to be the one to make the decision, it sounds as if he could really do with some help at the moment, I feel for you all as a family.
Your not whinging, your a caring Mum like the rest of us, take care and keep in touch.
