Hi Sharlieboo, Castaway and Synonym,
Thanks for your responses. It's good to know I'm not alone. I have to say I was beginning to feel a bit down and out about all of this as I've been off work for the past 4 weeks (to give me time out and try to get my levels down), I'm not sure yet whether I'm ready to go back, but I'll see how it goes.
I've been whizzing around the forum as you have suggested and I can see there's loads of helpful advice and tips, which I'll be making use of. Thanks again, I'll keep you posted.
