I can't advise on the FAA but
If you are 16 and your blood pressure is normal and you are coming off drugs I would put my medical license on the line and say you have never had hypertension
You don't get high blood pressure at your age unless you have one of a number of serious conditions that don't simply go away. In fact most get worse and fast
Go buy yourself a blood pressure machine at Walmart and take your blood pressure a couple of times a day when you are resting. My guess is you don't need drugs, there is nothing wrong with you and the FAA will love you
Having said all that I can't advise you to stop medication unless your current doctor or a second opinion so advises
Good luck
