Hi
@Lesleywo,
Have you heard of diabetes burnout? There is no particular time scale for when this happens and if you are a perfectionist it seems more likely.
Read this article and see if you can identify with it

Do any, or all, of the following fit you?
1. You are often called a perfectionist. You may admit to this, or feel that it is a bit extreme, but you do like things to be 'just so' and are pretty highly motivated to get them that way.
2. You feel a deep need to succeed in everything you do, you are highly committed to that goal and if you do not achieve that success you feel inadequate and see yourself as a failure.
3. You need to have control over all aspects of your life. You want to make the choices, not have situations thrust upon you.
4. You find change, with it's related unpredictability, stressful.
5. You have extremely high personal expectations and tend to be very critical of yourself if you do not meet your own standards.
6. You have a tendency to take things personally.
