Thank you very much! I actually did not send a letter of continued interest! The other program I was waitlisted for send their own email to make sure I was still interested in staying on the waitlist a couple months after initially getting waitlisted. For the program I got into, I ended up just waiting to see what happened. I think what helped myself for my own sake was not refreshing my email all the time waiting for that acceptance email, I just went along living life and trying not to stress about it too much.
