Why do I feel nauseated in pressure situations?
human
When I feel I am in pressure situations and I become so tensed  nervous my palms and foot goes cold sweaty and when I stand my feet shakes, my heart palpitates, and I go in a state of trance when i could not memorize the things to be said or written in (exam, presentations, etc). Specially in situations where I don't know what to expect. I have nausea when I am nervous.

Hi,It seems you are suffering from anxiety disorder with performance anxiety predominating. You can chose to start management with medications or behavior therapy or both combined. I would advise you to meet a local psychiatrist. One of the SSRIs like paroxetine would be a suitable agent for you. In addition you can start doing some relaxation exercises like progressive muscular relaxation which will help you relax. Wishing you speedy recovery.
