Im 17 and i have a rapid heart beat  quite soft every morning , i was told to take a blood test they said that everything is normal but there's this feeling inside that says try a cardiologist i was told i had acid reflux then the pills i was taken wasnt allowing me to sleep with serious headaches so i went and see a private doctor and he told me i needed blood work and a thyroid test he give me a prescription for anxiety and said my blood was low so  vitamins for low blood thats when i took the blood test just yesterday and he said it was normal and woke up this morning with the rapid soft heartbeat and obviously panic then felt dizzy a little so i rest

First that happens to a lot of people waking up and the heart rate is little elevated its normal.It is physiological phenomenon of coming out of sleep state to waking up state.Second don't panic about it as you might develop anxiety and that means higher heart rate. So when you wake up just seat on your bed lean against your head board and relax for few minutes.Your HR will come down.
Anxiety and panic will make you feel dizzy and nauseous.
Then again get checked by another doctor even a cardiologist  for a piece of mind.You are to young to worry

Have you ever had your thyroid tested? That is a common symptom with hypothyroidism. Just a thought.
