I too have feelings like this, usually when I am inundated with my work at the time, but I am fortunate enough that when I am on song at work, I can put it behind me.
What I do find is that I also experience symptoms like this when I am lying in bed at night, awake and thoughts of my childhood come rushing back. I suffer anxiety, depression and PTSD from my experiences as a child. It makes it ever increasingly difficult to cope with day to day activities, especially when I had shut it all out of my life for 20 years, then one day it all hit me in a way I can never forget.
The stress will fuel the anxieties. I find that myself at work, then they start feeding of each other, and unless your colleagues all know whats going on inside your head, they will just think your crazy.
I have found the best solution for management at work for me is to tell everyone what I suffer. Whilst it isn't on my email signature, it comes up in conversation and I don't hide it. It is amazing how much easier it is to deal with the symptoms at work when you don't have to hide them. All of a sudden things do not appear quite so bad (mostly).
All the best.
Hi name is Dave and this is my first post! I have has a couple of "minor" panic attacks in the last few years but last Friday night out of nowhere I got hit by a freight train of a panic attack, it was so intensely overwhelming and I really thought my mind had snapped and I was going crazy. I can relate to your experience greyhorse, because they were accompanying physical sensations- I couldn't stop shaking, I had a bit of a sweat on and I was afraid to stand still. It was only a few days ago but I've spent the last few days in an ongoing but ever- decreasing state of fear. I'm not so much afraid of a panic attack as I am of the feeling of disconnection- a feeling of being crazy for want of a better word. Like you I'm just totally over it and want it to stop. Ive booked in to see a psychologist and im sure this will help. I hope our shared experience can give us both hope. Good luck!
