question: I've been feeling ill for months.  Feel sick immediately after eating - sometimes I vomit - sometimes I manage to keep it down.  I have bloated upper abdomen all the time.  I get chronic pain in my upper abdomen that lasts for a few hours - if not all night - this pain does not go away with pain killers.  My doctor suspects an ulcer and has tested me for H pylori and a full blood count.He has written to me to ask to repeat the full blood count and has not told me why.  I have rang the doctors and they will not tell me why the retest is required as the doctor wants to see me by appointment himself - I can not get an appointment for over a month.  Im scared this could be cancer.  WHy cant they just tell me on the phone what is wrong with me???Im sleeping 10 hours a day - but IM still absolutely exhauseted all the time.  I have no erergy to do anything.  IM so tired my vision blurs.  I sometimes pass blood with stools.  I feel gereraly unwell.I have no neglected myself - I have been to the doctors many times over the last 6 months - they keep trying different medications - but no one can really say what is wrong with me.
