While I know a couple of people who have it way worse than I, I experience anxiety on a daily basis, all day, every day. It’s something that I’ve learned to control, yet am aware it affects me in a negative way. Sometimes it requires medication, though luckily this is fairly rare.
However I believe most people either have no idea what people with anxiety tendencies go through, or they don’t realize the symptoms of anxiety.
I ran across this video today that explains this quite well. According to this video 1 of 4 people experience anxiety in one form or another. Perhaps it’s worth a watch.
