Phone Anxiety

This is a bit of a weird topic to post on this app but does anyone else struggle with booking appointments or calling people who aren’t close friends or immediate family? I literally can not get myself to pick up the phone to book an appointment and I’m almost 19 now so my parents thinks I’m being dumb and lazy but they just don’t get it. My family does not understand anxiety at all in any circumstance because they have never experienced it so they are very closed minded. I’ve been able to get through with just being known as shy for my social anxiety but for this phone anxiety everyone just thinks I’m being dumb. Has anyone been through this too??
