I just had the worst presentation in my life

I just had the worst presentation in my life It was an over 20 minute long presenation. Days before my presentation date I told my teacher about my social anxiety and that I have a terrible stutter during presentations. She told me she would let me present in front of her and just 2 other classmates who also have issues and didn't want to present in front of the whole class. I was relieved thinking they would be just like me and that I'm not alone. But they presented fluently with no issues and without having to read from a paper which just made me even more nervous and it destroyed my confidence. I was the last one to present and I did HORRIBLE. I couldn't even talk freely, I stumbled over words, made grammatical mistakes while speaking, kept forgetting what to say or how to finish the sentence... it was a disaster. I had to pause for a few seconds multiple times because it got so bad that I couldn't keep talking. I ended up reading from the paper for 10 minutes... and my stutter got even worse. It was so embarrassing that I turned red during my presentation :/ I just want to crawl into a hole and slam my head against a wall or something.
