Dear Diva,
very nice of to answer me!
When I have asked this to psychoterapists, they also have confirm it is not dangerous for health but I somehow don't believe it. I think they are lying to me because they want me not to worry about it. Although I know it is nonsense, it's hard for me to tell myself- ""IT IS NOT DANGEROUS. IT IS JUST AN UNPLEASANT FEELING". I am very untrustful (if it is the correct word). My thoughts are very negative. Why? From where it is so? I can't stand it!!!
Thanks again, Diva, for your friendly and caring attitude!:)
