Hi OBrendie,
I have been off work since August due to my panic. My panic attacks are triggered by work situations as well, so I know exactly how you are feeling.
My tentative return to work date is November 15. My psychiatrist and I are keeping a close eye on my panic attacks. The panic diary here is very useful and we both rely on it quite heavily. My psychiatrist feels that it would be 'safe' for me to try and return to work then as my panic attacks have been small and manageable for over a three week period and it's a good indication that I should be able to cope with the work triggers. As well, I'm also pregnant, so that is giving me something else to focus on.
I'm not sure how your medical leave plan works, but I have an 8-week period in which to gradually phase myself back into work on reduced days and modified duties. If you have something like this - use it!
I know exactly how you are feeling. I am scared to return to work because I'm not sure how I'm going to react going back. My husband and I have already decided that if I cannot go back, then I will just stay at home on sick leave until the baby is born. Removing the pressure to perform and get back on my feet has helped tremendously.
I hope this is helpful. Good luck and remember to take all the time you need to recover.
Sarah :)
