Depending on how bad the rash is and how long you've had it, I would see your GP or a Dermatologist regarding this. It could be a number of things, and you need to rule these out first.
I have been going to counseling for depression and havent changed any products that I use.
I think it would be good to see your doctor to rule out any other cause before assuming it's anxiety. It could be a new soap or make-up causing the rash. Anxiety does manifest itself in many ways, but you want to make sure it's not something else first. If it turns out to be anxiety, please come back.
