Please let us know how things go, Pollaidh (I do like your name!) I have no strategies for coping, unfortunately. I often find myself muttering, "it'll be alright...it'll be alright", and I think that really is because after all the trials (mainly) and tribulations, I think things do end up being 'alright'.
Like so many of us here, my family have had ups and downs. I've done what I could to help, and they know I'm there for them, but I have to say, in my experience, that throwing good money after bad isn't always the answer. I just can't afford to do it any more now anyway. There are usually ways of coping without having to do that, if the right agencies are contacted, depending on what the problem is.
We're here for you to talk to, so blether away. I remember being absolutely frantic with worry one night, and I logged on to Gransnet and spoke through how I was feeling. Maybe it was because it was in the small hours that I felt more able to do it - things always seem worse during the night, don't they? Anyway, within less than an hour or so, replies to my post were coming in, and I got such comfort from that.
