Hi CMG,
I'm sorry to hear about your anxiety. I hope that your diagnosis leads to you receiving support from a professional and from those around you.
It sounds reassuring that your boss knows of your condition and is willing to change things around to help. Have you made any requests for how you can be accommodated?
You must be feeling somewhat pressured if you work on commission. Is that in addition to an hourly rate? If it is, I could maybe recommend being kinder and easier on yourself, even be lighthearted about the commission making side of work. Don't pressure yourself to meet unfair standards, but certainly challenge yourself a little. Maybe if you miss a sale, laugh it off and say big deal, there will always be more customers.
If your income is purely commission, I'm sorry that you are under that pressure. I really wouldn't know what to say to help.
On top of what WK suggested about deep breathing and taking care of yourself, I would recommend mindfulness. Practice it as much as you can and try to do it at work. Don't think internally at work, don't be mindful of yourself so to speak, but instead be mindful of the "non-threatening" things around you at work (objects, sounds), maybe not people if they cause you anxiety.
I hope you learn to cope better, or find something less stressful (it's ok if you can't cope there, it doesn't mean you're a failure).
