I first had anxiety around 5-6 months back, and after spending a lot of time and effort dealing with it i am 95% ok now.
Since iv had this horrible experience, I have since reaslised that 5 other people, in my workplace alone, have also sufered or are still suffering anxiety problems.
I work in a very professional company, and there would be no way of realising that these people were having any issues at all.
I am very close to a few work friends, and have discussed my feelings over the past few months, and I was very suprised to reaslise how common it actually is.
