I just went back to work myself after being off for 8 months (in school) and 4 months the year prior to that. Trust me its been very hard doing going back. That is why I am here right now, well that and I never got better just got good at pretending and consuming intoxicating substances. But I have a 90 average in computer networking and work for the health system in my area. You need work, just as I know I need it. Your problem isn't with working it is fearing you will have an anxiety attack. Which could happen anywhere at anytime. Learn to understand that and you will be able to cope. I get about 3-4 major attacks a week. I learned the hard way that running from the place you are having them makes you think the place is the problem. And its not you are. I know it sounds lame but breathe it out if it happens. Just remember what is the worst thing that could possible happen. You loose your new job and your back to where you started. Well just try again.
