High Blood Sugar. Called in Sick. Acceptable?

I've never called in work before on account of my diabetes (Type 1). I woke up this morning with very high blood sugar(30+). After an hour of pacing around waiting for my blood sugar to drop. I made the decision to call in sick to work and take the day off. I felt stressed, dehydrated, tired, high Strung and an overall bad feeling. This type of situation has happened to me before but I was able to lower my blood sugar and relax myself.

I rarely call in sick but I transfered to a new Department six weeks ago So I feel alittle more pressure to go in.

I take a lot of pride in controlling my diabetes. Maybe I'm just feeling guilt and shame. I'm just curious if any other diabetics have called in the sick before because of this reason? Is this an acceptable reason for me to have missed work?
