Yes, you need to see someone today (hopefully you already went). Have them check your kidney function. Since you're so young, it would be uncommon to have hypertension that isn't being caused by something (primary hypertension). I have secondary hypertension. They found that I had a kidney problem that wasn't discovered until I was 19 and started experiencing high BP.
I am not trying to scare you, but BP that high can cause a heart attack or stroke so please get seen ASAP. If 4 different meds aren't controlling it, then something is causing this (kidney problems, adrenal gland problems, etc).
Good luck
You need to see a doctor ASAP. If you are on 4 BP meds and your BP still rises that high you need to see a doctor.
