Application question

So long story short I got a job this past fall at a Med Telly unit. Everything was fantastic in the unit. The nurses, managers, patients (most of them), MDs and other staff. Once the amount of patients I had kept rising, I started getting into a habit of taking my time documenting at the end of the shift and getting out pretty late. After a while my preceptor noticed my struggle and was giving me tips of better time management. But whenever I improved in one area I would side swiped by a constant need for jello and yogurt, or a new admission while a patient's overdue meds was to be taken. While I did fine with 4 and sometimes 5 patients (depending on the patient case, there would be a noticeable struggle with 5-6 which is the norm for the unit.

So when the orientation period came to an end, I met with my floor manager and ANM and they said I performed very well and my coworkers and patients liked me, but I needed to reflect on my time management. Should mention this is night shift 7-7. She said I should still apply for the next program and just reflect on my skills gained in the unit and use her as a reference.

This is where I'm at now. It's time to apply and under work experience I put in my information with the Med Telly unit. Theres a box that has a drop down list that says "Reason for Leaving" and a text box to put it a comment. My question to all of you is should I even include my time in Med Telly or no because I feel like it might affect the nursing managers' decisions once they see that I couldn't even survive a Med Telly unit (Not that its not a difficult unit, everyone just always seems to put it as a bottom of the totem pole unit in terms of intensity) I'm having a hard time thinking of what to put in the comment box. Any advice would be helpful THANKS
