Good Morning Em and welcome to HealingWell's GERD/Heartburn Forum.
I am sorry you are feeling so down re your GERD but I do agree with your Doctor to give the medication a chance to kick in.
You are right, the AD meds take 4-6 weeks to kick in and you may be OK once the GERD settles down so I would give it a bit more time. However, if you still feel you would like to try one of the ADs do talk with your physician.
We have a great depression forum here also if you want to talk about your feelings with the members of that forum you are always welcome.
