Suffered from dizzy heads and panic attacks and at one stage managed to convince myself that I had a brain tumour, as was getting headaches and weird sensations in the head. I have my appointment today and for the past few weeks I have manged to sort myself out a little and try to relax, but now this appointment is so near I feel really awful, I just think I will go and they will want to do a scan and this nightmare will go on for weeks/months.
