A few things come to mind. I know which threads you are referring to. The OP has a habit of posting slightly strange questions without following up on the answers, or posting questions that have been discussed literally 2 threads up. At least it has been this way since I'm around. The OP has gotten some advice, but did not really answer again. So what more is there to say than "go see a doctor"? The health problems he discribed are normally easily deal with by any GP.
@ego - have you ever pursued a diagnosis for a mental health problem or tried to get qualified help for such issues? I think most people who have done so would agree with me that you are mostly on you own, unless you are content with a prescription for anti-depressants (not that there is anything wrong with taking some!).
The amount of energy it takes to even find help and to get this people to take you seriously is often more than a person in mental distress is able to bring up. People tend to take you seriously if there is something visibly the matter, with mental illness you have to fight for yourself a lot, which makes validation from other people with similar problems so valuable. Hence there is a great need of discussing this often taboo like topics with other people who know what it feels like.
Furthermore, I'm not comfortable to give advice on health questions if I have not a) experienced it myself and b) done a lot research. Should anyone need advice on migraines, food intolerances or reflux, bring em on!
