I suffer with a very similar thing. I find it extremely hard to have meetings/discussions with people in work as I am scared I will have one of my panic attacks. Mine are very visible, and I start shaking but also retching and dry heaving and find it extremely hard to control. Most of the time the only thing I am actually anxious about it having the panic attack and someone seeing and thinking I am really strange and weird.
It is getting me really down and depressed and I am concerned this is now my life and it will dictate my whole life forever.
I don't know how to control this, and am sick of feeling like this. Not only is it mentally exhausted but physically also.
I have joined this forum today and really want to talk to other people about this, and am looking forward to hearing people's experiences/comments etc.
