Yeah, since I started uni, anxiety (and just generally heightened emotions, actually) is definitely something that has either developed or that I can now identify in myself. It's not too severe, but there have been a couple of instances where my heart rate has gone up to an uncomfortably high level.
if it's only certain situations (for me public speeches), betablockers are the best option. they don't mess with your brain and are not addictive, but help your nervous system relax. when the body does not stress, the mind will follow.
