Difficulty swallowing, bloating and burping.

A few weeks ago I started to experience difficulty swallowing. I can feel my food slowly going down in my chest and sometimes it feels like it’s stuck there. I also starting burping like CRAZY. I have a small sip of water and immediately burp and feel so bloated. I have been losing weight because I just don’t want to eat anymore because of it. I am 31 and have has mild reflux since I was 13 but it’s been super manageable to the point where I typically don’t need medication. After I had my sons I noticed a huge increase in symptoms and my doctor told me I could possibly have a hiatal hernia from the pregnancies. I made the mistake of googling and all I see is cancer or barrettes esophogus coming up so it’s causing me anxiety. I have a doctors appointment on Thursday to discuss this with my doctor but I was wondering if anyone else has gone through this as well? I don’t know anyone else who has had this issue before so I’m panicking a bit.
