Leapers, please do be assured that whatever your problem is, don't be embarrassed at sharing it with your GP- the doctor is used to people not wanting to share things which are worrying them. You just have to be honest and come out with it - you might not want to say whatever it is, but the doctors have seen it all. If you are afraid that it is something bad then don't wait any longer, the longer you put it off then you might be harming yourself, or preventing yourself getting some treatment. If you are really stuck about talking about it, then write it down and hand the note to the doctor when you go into his room - you might find that a bit easier to tell him/her what you are worried about, if he reads it rather than you speaking about it.
