I have some sort of huge chemical imbalance or/and limited blood flow in my brain.  Symptoms include foggy mind, tired, horrible memory, low mental energy, blank mind, dizzy, buzzing in ears, concentration, its very hard to function and do anything as my mind finds even simple tasks to be hard, time is hard to judge. if i drink a beer i become instantly impaired beyond what one beer should do.  my school and social skills have completely crashed everything is different than it used to be i feel like the doctors I have seen are too quick to tell me Im depressed to get me on drugs before they really look into the problem A recent MRI came back negative for brain damage.  Is MRI a good test for my symptoms What kind of tests would be more appropriate for my case ? what symptoms would I experience if I had a blood flow problem.
Dear, You did not mention your age. Half knowledge about body functioning is like having no knowledge at all, It can create stress and anxiety which now you are facing. If you want to clear your doubt, consult a physician first. No self conclusion. It can do more harm than good. You are not your doctor. There are people who are qualified. Consult them and get to a conclusion and worry if you have to. If your MRI is clear, and you have some problem other than that, your doctor should advise you. This might be stress and anxiety. Still not sure then check with your colleagues and consult a neurologist. But believe him because he is qualified, not you. Wish success.
