Occasionally you'll hit a really tough part of your course and you'll want to have a mini-meltdown.
1. Send an e-mail with your question(s) and then keep moving forward with the next thing. Review the guidelines still one more time. Read them out loud. Even type them out. You may have an 'aha!' moment.
2. Get your calendar and make a note 3 weeks from today. Let's pretend, for the sake of our discussion, that your mini-meltdown is related to MENTAL DISORDERS or NEOPLASMS (for coding students) and LABORATORY REPORTS (for medical transcription students). Your note should say something like, "If I am still having trouble with [insert topic of mini-meltdown], send more follow-up questions to my instructor and explain that I've had this problem for 3 weeks now and it's still bothering me." Even put a frowny face on there if it helps. Then, move forward with the next thing.
Most of the time when I ask students how they are doing on those horrible problems, they say, "What problem? I'm not having any problem." I remind them, "The problem with Neoplasms." They usually say, "Oh that! Something just 'clicked' and I'm not having a problem with it now.
Also remember that you are learning at the professional level, the level that experienced coders are at on the job, not the introductory level taught in most courses. That means that it IS difficult, but it's worth doing.
Try the calendar technique. Why? Once you've written the note, that energy you were wasting on how to respond to that problem is now released so you can move forward in a more productive way. You can wait and take action in 3 weeks if it's still a problem. You don't have to lose sleep about it.
