Really needing some hope and guidance right now

I’m a 45 year old healthy female other than what I’m about to say. I have been exhausted and had trouble swallowing food and drinks for maybe about 3-4 weeks and had an endoscopy this past Wednesday. I was diagnosed with invasive esophageal adenocarcinoma, moderately differentiated Friday and still waiting for HER2 results. I do not know what stage I’m in. I have mild gastritis and it started with food and drinks getting “stuck” and I would regurgitate lots of foam, food, and mucus with bubbles. No bitter tasting acid reflux this whole time. I had gastric sleeve in 2021 and have had silent reflux and gastritis ever since, for which I was taking panteprozole. I am scared to death because the outlook on this type of cancer sounds grim. I’ve heard once symptoms start, it’s already advanced. I live in Birmingham, AL and can’t afford to travel or live in another state for treatment unless it’s Atlanta. I just need reassurance and recommendations. Also since the endoscopy I have been able to eat soft foods (which was not possible last week) and drink with no issue. no mucus, no regurgitation. I’m still burping foam and feel a gurgling in my throat. Dr said he was not able to dilate because of the inflammation. It’s all so weird and hard to take in right now
