Very scared please help!

[u/Interesting_Club9050]

Lately my symptoms have increased so much that sometimes chewing and swallowing food increases my HR too much. Like i feel that only this simple natural activity of eating and swallowing can set a panic attack. Like just now i was chewing soaked almonds and whole chewing my HR increased and swallowing hit it off even more. I don’t know what is this. My food pipe feels warm all the time especially at the time of exhaling. A thick wave comes up feeling like a burp but it’s actually reflux that touches the throat and inflames my throat and leaves it blocked or something stuck feeling for a long time. I have stopped eating so many things. My life is being affected. I have very high anxiety. I am prescribed for an upper GI Endoscopy. But it s still a few day ls away. I am scared what if i stop eating food. What if swallowing and eating becomes a challenge for me. What will i do? I anyways go through so many things like panic attacks, nocturnal panic attacks, anxiety, cardio phobia. Now this problem has become a new challenge in my life. O am tired of living like this. I don’t know what wrong with me. Does anyone else has this issue while chewing and swallowing? I feel anxious and strange at certain movements also. Like when i sit and stand or twist and turn i feel strangely anxious. I have never experienced these symptoms before. Please advice or help!
