Hello and welcome to HealingWell,
I am sorry to read your job is stressing you out. A couple of things re your job - is your supervisor under union contract or management? Also wondering how your contract job description reads as far as your duties if you are being assigned duties not in the job description ?
Also have you seen a therapist to help you work through your problems ? Many of the members in this forum have had success with therapy including myself.
CBT = Cognitive-behavioral therapy is based on the idea that our thoughts cause our feelings and behaviors, not external things, like people, situations, and events. The benefit of this fact is that we can change the way we think to feel / act better even if the situation does not change. There is a free online site that you can work through from home using your computer. Here is the link for the site: http://moodgym.anu.edu.au/welcome
I hope you can work things through and also remember we have a forum for GERD so do visit and post questions in that forum.
Keep on talking with us and know we care.
Kindly,
Kitt
