Are you suffering from a broken heart? Searching for the right medicine? Staring down the barrel of being single and not knowing where to start? Learn from Grace Callaghan She's done it all: * * Wine is the answer. Some serving-size suggestions include: a glass the size of your head, a bathtub, an Olympic-sized swimming pool. Best served chilled, and with a straw. * * Friends with benefits is always an option. Be prepared for side effects such as the guy saying 'baby', crying out his ex's name and preferring to keep his socks on. * * Going 'out out' helps banish the blues. It may involve breaking into replica ships from the fifteenth century, screaming 'Aye-aye, Captain ' and accidentally falling off the plank. * * Karaoke makes everything better. Best enjoyed singing Enrique Iglesias, followed by an extra-large serving of fries.Three years ago, when Grace's heart was blown to smithereens, she made a promise to protect herself. But has she gone too far? Has she played it too safe?
