My anxiety is very physical compared to mental. I often have a pounding heartbeat, or it's just harder/faster than normal (had tests and my heart is fine). I feel like there's a lot of adrenaline in my body, and I know beta blockers stop the adrenaline from affecting you and it slows your heart rate down. I asked my GP for propranolol (a beta blocker), and it's only listed as an anxiety helping drug for ages 18+ (I'm 17). Its primary use is for heart disease but it is known to help with my situation too.
Is there any other way I can get beta blockers? Is there some other drug which I'm allowed to take and has a similar effect? I've been pretty miserable for the last 3 months, so it is a bit of a last resort to help me through this time.
