What do you think is wrong?

So i went to my doctor on tuesday(May22) with symptoms of pain when i eat, swallow, drink in the bottom of my esophagus and mid chest. I weighed 123 and i wasn’t eating because it hurt too bad. She prescribed Zantac for GERD and i was okay with it. Today, (friday,May25) i went to urgent care because i had lost 10 lbs and my dad was concerned that i wasn’t eating anything but jello. (jello hurt the least to eat) So this different doctor prescribed Prilosec and said i was supposed to take it tomorrow morning, and he said i had Esophagitis from GERD. I’m curious to see if that’s all it is, because my sister has GERD as well. The emergency symptoms are vomiting uncontrollably, (i haven’t thrown up yet, so if i throw up he said to come to the er so he can scope me) And if food gets stuck in my esophagus. Let me know what you think please!
