Slow down and breathe and put it in perspective, hon. Both aren't due today or tomorrow. That's a positive. Another positive--you are performing. Another positive--it sounds like it's one of your songs you are performing. Another positive--you are getting help with the assignment. Another positive--you know that you have the option of not performing if you choose. You don't have to "come up" with a reason not to perform--you have a reason. You've been in the hospital (nobody needs to know why, not their business). It's going to be ok, these are things that are managable and if they seem too much, you now know you can call for help. I was in tears when I read your first post, so happy for you. Just remember how important and precious you are. And that is more positive and important than anything else. So breathe and take it one small thing at a time and if it feels like too much, step back.
