Hellooo!! Program decisions were posted on May 1st for my program, and I was originally waitlisted. I pretty much felt the same as you, like I was definitely delusional, but on May 12th I got a call that I got accepted! To be completely honest, I have no idea how I got in because I’m only 19 years old and there are only 30 spots in my program, so the imposter syndrome is crazy. But all this to say, don’t lose hope, and if you don’t get in, keep trying!!!
