« I know children deal with this etc but I'm just struggling. Anyway, that's it. If anyone has words of encouragement that would be nice

Sending many words of encouragement - was diagnosed at 68, while still teaching. You will get through this and in a couple of years time will look back and see how far you have come.
Have since retired, but still getting used to not having a set routine. Having to get up and show up and teach every day gave a shape to my then new type 1 routine. The principle offered to sign me off for a couple of weeks, but I needed to learn how to manage the condition for work. I only once had to go home early, when I had a yo-yo sugar day!
I couldn’t believe I had ended up with type 1 and asked a doctor in the emergency room if I would lose some more weight, eat more sensibly and take a bit more exercise I could quit the insulin. She deliberated a while and said «No!». A fortnight later I got a phone call from a professor at the hospital confirming what I had then worked out for myself that this was type 1.
By chance I had a holiday booked with my then 14 year old grandson , touring northern Europe, mainly by train, starting just a fortnight after diagnosis. I think otherwise I might have sat home, it was school holidays so I wasn’t working, overthinking my new situation.
I shudder now to think of the situations I ‘got away with’ on that holiday. I had a glucometer and two sorts of insulin and had received three renditions of what was obviously a standard warning from hospital staff about drinking alcohol, or rather not drinking alcohol. It was some months before I ‘dared’ to risk a drink of any kind, but fortunate that holiday was with underage grandson. So wine with meals and a bar in the evenings were not elements of that holiday.
Afternoon naps and regular meal times were!
I remember the realisation that spontaneity was being removed from my life. I am currently trying to get into the routine of a daily walk, for a while my DH insisted I kept to the roadways, rather than footpaths. But with a CGM and jelly babies, I am back trekking footpaths.
Make use of the tech and be kind to yourself. The DAFNE course will teach you some practical stuff and also give you a chance to meet others with the condition.
