Sometimes i get so nervous i faint, how do i over come this?

lOOKY :their are many jobs that people faint over , in your job to see some of the things you do see i am not surprise that you would faint.Right now I have two blood clots one near the heart and one near the brain i also have low blood pressure I use to find my self have gidizzy pains Bit as time has gone it I have moved into a stright blackout situation and it can happen at any place any time when i come around i mostly find myself in hospital , I think that in your job you sometimes are under the stress limit , The way i do it is to carm down and then seek help with my Phyicologist this helps me to calm myself down . now all i can surgest is for you to find out as to what the cause of the fainting is , so please go and seek help by seeing your doctor . peace.AS for being Dumb well you can get that stright out your mind , how can you be dunb in the work that you do , ?You should go and see your doctor and have your blood level looked at and even ask him for a referral to she a specialist
