MRI caused a massive panic attack

I was in a bad car accident a few weeks ago and had to get an MRI today. As soon as I went inside, the tight space became unbearable. I was fully inside, with my shoulders pressed against the walls, and all I could see was the ceiling. I tried my best to push through, even with a benzodiazepine to help me relax, but I physically couldn't do it. I ended up crying, which is extremely rare for me. The nurse made a comment that felt like they were calling me weak, which I found really unprofessional.

Is there anyone who overcame this?
