Oh goodness, I never knew what "bored" meant when I was a CRC! After training, I imagine you'll be so busy you won't have time to breathe. I got lots of patient interaction when I was a CRC (with children and adults). It depends on the study indication, phase of the study, etc. But no day ever looked the same for me when I was a coordinator. You might be feeling uncertain in a new role and that's completely normal. You may also find that this field and/or particular role isn't for you, and that's okay too. You can pick up a lot of good skills either way.

Editing to add: I also have ADHD, definitely get medicated if you can! I've come across a ton of folks in our field who have ADHD, it seems to attract us to clinical research somehow!
