My experience of the NHS in the UK is it's geared up to send people away, either with advice to check out the Internet, or to call the helpline (NHS Direct).
You have to show perseverance to get to the next level of care ... which is usually a proper (few minute) consultation. Don't even think you can actually receive medical care unless you can provide a convincing case or show of advanced symptoms.
A male friend who had not seen a GP for some several years, was suffering from severe depression and eventually went to see his GP, after a great deal of effort. He was sent away with a leaflet on symptoms and lifestyle suggestions.
