Loss of appetite and change in taste. I haven't eaten a meal sin...

Loss of appetite and change in taste. I haven't eaten a meal since about 26th March 2009. I have a sweet, sickly taste and I can only eat cornflakes or crisps. Cups of tea don't taste like tea and I try and taste different foods each day but still can't eat anything other than cornflakes and crisps. They have ruined my life and I have been told it could take 12/18 months so I have another 12 months to go. I don't think I can do it!!. I would love to hear from people who have had this problem.
