Your problem may be a vaso-vagal syncope but you would probably understand that it is impossible to make a good diagnosis with this kind of communication. There could be also other reasons for this kind of symptoms and therefore you should see a doctor who would take care.

I generally suggest seeking initial help at the Primary Care Doctor. She or he would refer you to a specialist if this is necessary.

Last but not least, I am a surgeon. In the surgery, we don’t have so much to do with vaso-vagal problems or reasons for fainting unless there is a clear underlying vessel problem which could be surgically repaired.

You are actually in a healthcare oriented college, so it shouldn’t be difficult to find a good doctor who would address your problem.

I hope to have been able to help you.
Best wishes and good luck! :)
