I second
@RAPS_od 's suggestion about peer support and evening primrose oil.
For another angle on bsl control, as a suggestion you may wish to look up True Grit type 1 - an American website. Controversial to some but based on the work of Dr Bernstein and his book Diabetes
Solution.
A diabetic on insulin now for some 75 years, Dr B advocates a low carb, high protein diet which has the potential to keep bsls in good control with fewer and less severe hypos.
The website has adult and child diabetics who post on it. A blog site called drdavidludwig.com describes an article about adults and children on very low carb diets having very good HBA1Cs and very low hypo rate, from a survey if diabetics who follow Dr B's principles ( the survey included examinatiin if the parient's medical records so there was firm data to bsck up claims.
The contraversial part is that a) many doctors and Dietitians do not believe in low carb high protein diets and in adolescents they pontificate about whether such diets affect growth b) the lower insulin requirements are also queried regarding growth as insulin is a type of growth hormone which makes sense if you think about thevdose going up in growth spurts, too. c) there is still a widespread belief that increasing protein and also fat intake when on a low carb diet increases risk of heart and blood vessel disease, cholesteol up etc..
To countervsome of these concerns A) and B) parametrs of the diabetic children surveyed about show no problem and on a slightly different tack, Inuit and Laplanders have survived very well for centuries on a zero carb diet. It was when Western foods came along ( carb laden) that diabetes and heart and blood vessel and obesity problem devloped
C) if you subscribe to zoeharcombe.com, you will be treated to a tour de force of rebuttals of the lipid hypothesis, the idea that saturated fat and chilesterol causes heart disease. Zoe is a nutritionist from Wales, whise PhD was about saturated fat and heart disease. She shiws up the flawed statistics and reserach behaviour if early and mire recent studies on saturated fat, cholesterol, stsins and the attemots to discredit low carb ir liw carb high fat diets LXHF) as they are often called.
There was an article in the Lancet journal last year saying low carb diets are associated with higher risk if heart disease and Zoe debunks this, shiwing how stars have been manipulated to give the finding which the authors desired.Many doctors are nit au fait enough to understand the stats ir bither to look at rebuttals but quiting her work, getting nurses and doctors to read her work her work are great ways to get them to see the ither point if view ( of course minds are like parachutes, they only work if open.
So in that misnomer called spare time (lol) you might wish to see what the True Grit people do and hear Dr B's talks. He is a bit garrulous at times but lots of pearls of wisdom.
The downside of the site is that they are selective in who they let post on site. I have not been able to earn that right as i have only been on a very low carb diet for 5 months. But by contributing to comments on site you may be able to get some responses to help answer some queries.
Also let your daughter know that some of us TIDs on disbetes.co.uk have had diabetes and been on insulin for 30, 40 and 50 years or more ( me 52 years) and went through teenage years without cgm, pens, fancy insulins or blood glucose meters.
And have had minor complications only. I blame my cataracts on growing up and living in sunny Australia !¡¡
