Propranolol

Hey guys. Been thinking about finally taking my 10 mg of propranolol. I’ve had it for a bit and just nervous to start it, so I have some things I’m wondering about first. I have high blood pressure usually stressed out about something. I always feel a like heavy chest I don’t know how to explain it, I sometimes wake up in the middle of the night with burning legs or burning chest just stressed out bad. But I’m nervous to take it because I work a tough job, outside all day( linemen) working 10 hours grinding, heart rate is always sky rocketed. Do you think I should take it, because I feel like I would pass out because my blood pressure is low idk. Thanks
