GERD symptoms, really worried pls help.

I'm having GERD like symptoms. Acid reflux on a daily basis and burping very frequently even when stomach isn't full. Really bad coughing fits especially at night that sometimes lead to shortness of breadth and i have to mouth breathe for relief. I am always feeling like there's a lump in my throat and no typical coughing medicine has been able to help me. This has been happening for past few months, i initially ignored it since I used to live in a college hostel and didn't get proper diet but it's persistent now and I'm really worried about the continuous coughing fits. When i keep a sualin tablet or laung in my mouth only then I'm able to manage the cough and this I have to do about 7-8 times a day maybe even more. Please get back to me as soon as possible and let me know if i need a test done because it's really causing me a lot of trouble sleeping. (I don't know if it's relevant but i get panic attacks sometimes and when i do I cry a lot and thus cough a lot and belch a lot.)
