I must say that this is one of the loveliest threads I have ever read. Anth's anxieties have brought out the mothering instinct in us, and so many have chipped in with good advice, reassurance and comradeship - even the normally cynical folks.
My suggestion, for what it is worth, is a Marks and Spencer eat in for a tenner - remarkably sophisticated food, yummy puddings, a bottle of plonk that you can drink or choose not to drink, all whipped up in the oven or microwave in next to no time. (They do a really nice one for Feb 14th but that's not for while yet.) And dark Belgian choccies are a great aphrodisiac.
And the overriding theme is just to relax, enjoy the moment, and count your blessings!
