At the minute I ave to have my blood tested weekly due to my addiction to laxatives......now in the past I have given blood, and blood tests have never bothered me....but since i became ill back in February I have found that the sound of the blood going into the little container, used for sending to be tested, makes me feel nauseaus and I have passed out twice due to this......

Is this linked to the anxiety of being in the Drs surgery do you think?
