How come now that I'm back at uni and on campus that I suddenly have an overwhelming feeling of not wanting to tell anyone about my T1?
Also no progress on getting the levels down... now starting to wonder if it was the change to levemir that's caused this
Oh tell them, Jazz, you may one day need them to go get you a sugar-laden drink to get you out of a hypo. And they’ll also know, if you explain, that it’s your blood sugars making you behave that way when you get inappropriately cross or you behave as though you had a litre of gin for breakfast and you’re dripping with perspiration, or, as Oscar Wilde maintains, you ‘gently glow’. Unless, of course, you really are cross, and you realy did have a litre of gin for breakfast.
These situations can sometimes happen to us all.

Good mates will stand by you no matter what.
I suggest you tell the staff you have contact with too, and maybe ask for extra consideration while you get to grips with all things T1?
As for the change to Levemir, I doubt it’s the insulin: it’s more likely the doses you’re taking. I presume you’re taking 2 doses at approx 12 hour intervals? Levemir doesn’t last for 24 hours. It took me about 2-3 weeks of testing and juggling doses to find the right amounts after I changed from Lantus to Levemir.
It’s still early days after your diagnosis and it may be good not to reduce to ‘normal’ blood sugars too quickly as it’s believed that this can cause organ probs. Have you asked your DSN for help?
