Sorry if this doesnt make much sense, i’m relatively new to this and don’t really have anywhere else to ask. Does anyone else have experienced anxiety attacks without physical symptoms? For me I get really anxious for a certain period of time (several hours a day) where I get an irrational amount of fear about something (either towards taking a test, calling or emailing people). In those hours, I become much more quiet and I just can’t do anything that I feared of, even when I’m usually such a productive and responsible person. 

I really don’t experience any physical symptoms, except for maybe faster heart rate. Would this be included as anxiety attack? Do i really have anxiety? I know the answers are not official diagnoses of my situation, but I’d like to hear your opinions if possible. Thanks guys.
