Im 18M 65kg 5'8 , in start of this year experienced extreme gastric issues and high blood pressure 139/99 .i did manage to get my blood pressure and GERD in control in few days with exercise and gastric medication . But my heart rate is still high which has caused me alot of stress . My resting heart rate is 84 whole standing is 110  and i experience palpitations as well . 
I went to a cardiologist who did an EKG on me while my heart rate was high and i had what they call a sinus tachycardia , my Heart echo was normal and surprisingly my blood pressure in his office was 120/80 opposite of white coat syndrome and did a CBC which was normal , my blood suger was also 90 random

In march i started to experience what my doctor said panic attacks where my heart rate would jump up i would come extremely nervous and would think im about to die and my bp would shoot up to 140/90-100 . For which he prescribed me an anti depressant .. took it for few days and couldn't tolerate the side effects  one of them was hypotension where my bp dropped to 100/40 was on some drip in a walkin clinic right after the drip she measured my blood glucose it was 170 (probably because the only thing i drank in the morning was sugery mango drink 500 litre ) 
I then measured my blood suger  day to day after then but it was on the average low side like 80 to 110 and the doc was not concerned


 Due to the side effects of the lexapro i had to stop taking it . After few days of stopping anti depressents back in march i developed a dull like headache on my forhead and one side of my scalp . To this day i experience the headache every day and im stressed ..
I went to a neurologist whom suggested a CT and it was normal so gave me Depakote 250mg .. it made my headache less but also gave me irregular heartbeats and uncomfortable feeling in my chest so had to stop taking it as well . 
In the past i have tried getting rid of my molars with no relief
Muscle relaxants , pain killers and anti hestamines with no relief (only naproxen sodium helps) propranolol 10mg helps with heart rate but don't stop my headaches
 
I literally don't know what is causing my high blood pressure and heart rate and this headache and im very depressed at this point with no clue or a direction ..

 my new doctor has ordered a renal functioning test and another cbc after my bp was 130/90 at his office
