I think you may find some luck if you commit to getting over your anxiety. I have had issues with it on and off for years. Usually it starts up again when I do not use my skills. When I get in a situation like you do I pause, feel the anxiety, just let it do it's thing. It may take a while at first, you may not experience success with this the the first few times either. You have to stick with it and keep trying little by little it will get easier.

Once the anxiety subsides continue with your task. Consider reflecting briefly on what just happened, but do not judge the experience as good or bad. I will usually note to myself that 1- This situation has caused me anxiety in the past. 2- I have coped with the anxiety. 3- I have been able to get through it. Acknowledging you success makes it hard to not judge the experience, but I do not necessarily think this is a bad thing.

However, if you are not successful with coping with your anxiety I suggest maybe 1- Noting the situation that caused the anxiety. 2- Noting what happened and what you considered an appropriate success to coping with the anxiety. 3- Set a small goal for how you will do things differently next time.

It is a lot of work, but it is worth it. I have never used medication for my anxiety because I have been so dedicated to coping with it on my own (also I loved my job and using medications would put me in a no fly status and I did not want that).
