Hi Lone,
I'm sorry to hear you're struggling. I can relate to what you're going through.
I'm on medication, am highly anxious and get panic attacks, but because I pressure myself so much I also do well at work. It is very intense and exhausting though.
Do you get on well with your supervisor? If you do, maybe you can ask for feedback about your performance.
Do you get positive feedback from others? Keep a record of those messages and emails so you can reread them when you're particularly anxious.
My psychologist always points out that other people usually see us in a different light than how we see ourselves (usually much more positive, we are our own worst critics, even more so because of our anxiety).
Sometimes it helps me to observe others and their works and notice that they are not perfect either.
When I feel my anxiety increasing at work, I try to get some fresh air or even just go to the bathroom to do some deep breathing.
Just some ideas that help me sometimes and that you might want to try.
Hang in there.
