I have some symptoms, head feels heavy, I have heart palpitations

These are the symptoms that have been developing since early january..

This happend right out of the blue, and before all of this i used to go to gym, school, and work..

I stopped going to the gym and am now going to school and looking for a job

Symptoms:

-Head feels heavy and body feels light all day along with chest tightness and shortness of breath

-Headaches (light and intense from time to time)

-Insomina

-Heart palpitations (got my blood pressure checked, 124/83, but it feels like this at night and even during rest and sleep)

         - The pulse (very high) is what whats me up in the middle of the night 

         - If I were to walk short distances, I would become tired and my heart would start pounding fast

-Ringing in ears (I hear a high to low pitched buzzing sound through my ears all day)

-Balance problems (When I walk, I tend to lose balance and wobble and my legs become weak)

-Pins and needle sensations (When it gets hot, I feel it all over my body along with itchiness) 

-Numbness (Sometimes when I wake up in the middle of the night or mornings, one of my fingers would become numb)

-Spasms/Twitching (I believe i had muscle spasms once or it could be a intense case of tremors, but nontheless, my arms and legs were                               shaking, which lasted for nearly 30 minutes)

-Vision (I tend to lose focus, and my eyes seem sensitive to bright lights (I see zigzagging lines and bright flashes)

-Fatigue (I tend to feel weak and dizzy at times during the day)

-Memory and mood  (Somehow I developed short term memory and i get mood swings)

-Appetite (I lose appetite and sometimes I feel as if I dont need to eat anything at all and I would be fine)

-Eye (I feel eye pain from time to time as well, and sometimes while I sit down, I feel as if the objects around me are moving.

So far, I have seen a internal medicine doctor in which he said that I have anxiety (which I do not believe) and told me to see a psychiatrist.

I took a blood test and my minerals and chemistry is at normal levels, except for my magnesium level which is a little low

I have also seen a neruologist, I just finished my ECG tests, as well as a brain MRI, but I will not be able to know the results until my next appointment, which is in about 2 weeks. (too long for me to wait)

Medications:

-Xanax (Only pill that seems to be working 0.5)

-Buspirone (Made my symptoms worser, not taking it)

-Motrin (Makes me urinate along and the effects of it are okay....)

So I did some research and it looks like I have symtoms along the lines of MULTIPLE SCELEORIS, VITAMIN DEFICIENCIES, ANXIETY..

Could it be anxiety? I dont think it is because I do not feel any axiety (if anxiety is something one can feel) but when I take Xanax, everything cools down but comes back after the pill dies off..

Thanks.
