I really thank you all for your replies. Mr Clark you are right about what you' ve told me, i think i am really oversensitive with IIH now. When i'll feel completely normal i'll reconsider my decision about taking this course. But if i decide not to take this course i don't want this decision to based in this experience. At the end if i decide to take this course do you believe that through IIH steps,and therapists help, i'll manage to overcome my fears? Thanks again for your replies
