Pcb, i have suffered from severe anxiety too and so can sympathise with how youre feeling. Its isnt quick to fix but you can make a full recovery. There may not be a need to check into a mental hospital, i felt like doing it a lot of times in my worst states but that is based on a fear that you cant cope. That is also part of the anxiety and over time you will learn you can cope and how to stop the anxiety controlling your life. Your anxiety is there to protect you, it is trying to help, you just need to learn how to put it at ease. Youve got the endoscopy in a few weeks, just reassure yourself that you just need to make it until then, and then everything will beok. Small steps are the key. Take each day as it comes, set mini tasks, keep your mind busy but dont force anything. Stay relaxed and belive me, you will get throug this ok.
Your symptoms are very common, almost everyone on this forum probably has them. Still important to get an endoscopy and get it confirmed though, there are other conditions that can manifest as gerd (not deadly but difficult to diagnose) and they are teated diferently so its important to get the correct diagnosis.
Try relaxation techniques, i find autogenics very helpful for anxiety and it also relieves gerd symptoms for me so is doubly effective.
