I am another newbie to this site and understand your concern with the stress related to your job.
Work stress can cause panic/anxiety attacks. I have had this happen to me from time to time. This can be worse when I am run down (healthwise) . Know that the panic attack is about your reaction to being stressed not about your workplace/environment.
It may assist to manage this by calming yourself using breathing and relaxation techniques. Focus on being in tune with your body and feelings.
It may also be helpful to cut down or eliminate all caffeine from your diet. Drink water throughout your work hours and make a conscious effort to get plenty of sleep and rest. Be kind to yourself and be fair. You are working hard and I bet you are doing a great job!
Also make sure that you relax in your free time and take the opportunity to spend time doing things you enjoy!
I will follow this message thread as I am interested to hear what other helpful advice others have. Addressing stress in the workplace is something that I need to work on too.
I hope some of these tips are of some help to you.
