I have read a lot about people experiencing anxiety because they anticipate things happening, like being afraid of talking on the phone or being afraid of boarding a plane because it might crash.
I only experience anxiety when certain things actually happen. I get anxious when I'm concentrating on something and it's repeatedly interrupted, like someone calling my name 2 or more times while I'm busy doing something else or an alarm or phone ringing nearby for a prolonged period of time with no one picking up the phone or turning off the alarm.
I work at a busy cafe and I get anxious when I'm working on something and three or four people crowd me and I have no room to move. I have no fear of crowding otherwise, as I go to concerts wall-to-wall with bodies and think nothing of it.
I also experience anxiety when I drop things or when I stub my toe, to the point of being momentarily overwhelmed by it and having the urge to lash out physically. The same thing happens when I'm trying to arrange something specifically, like hang a picture frame or style my hair and I keep experiencing the same problem over and over again. Or, when I have to tell people the same thing repeatedly or hear the same story more than twice.
Is this anxiety or something else? I don't ever experience fear as a result of these events but I do feel panic, like there's an alarm going off in my head. Sometimes it will leave me feeling sick all day and I'll tense up and look really formidable or angry when I'm not.
