Thanks so much for your replies - it really helps!
I like the idea of focusing on just getting through one day at a time - i tend to think about so much stuff at once and take on a lot all at once so this time i will just try to think of the immediate future and the present moment.
I will also get rid of the alcohol in the house and take the kids on a walk this afternoon instead of having my usual "glass of wine to unwind after a busy day"
