I'm sure everyone, you included, is frustrated. For me personally it was rather upsetting that I, along with several other people, had told you to immediately turn the uth off. You didn't do it and a few days later I come back and see the snake with an even worse burn than before. Really frustrating as an outside observer who gave you good advice that you didn't follow. It was sort of like why did you even bother to ask?
As for you I can certainly see how some of the comments would seem insensitive and even provoking, but I'm confident that the posters have the best interest of your snake in mind. Harsh yes, but the comments didn't seem to get through the last time so there is a sort of urgency to impress upon you the need for proper care.
When I first got into the hobby some of the terms were very confusing. I did a lot of reading myself, but unfortunately sometimes you don't learn things before you experience them. Chuck this one up to experience, learn from it and get on the ball to make sure you don't do it again. I believe that you have a promising start and I look forward to seeing your BP's progress as she heals. Best of luck.
