Nosebleed Advice

Hi y’all,I’m planning on going to a Ravens game sometime this season (Bills,Commanders or Eagles). Now im not a person who earns great income so I’ll probably be sitting up high. I’m not really good with heights. What can i do to prepare for a higher space at the game? How are M&T Bank Stadiums upper levels? How secure do you feel when sitting in the 500’s? Thank you for any advice. Its well appreciated.
