Heya
@Laurenbrown1 I think we all experience lots of things after diagnosis, such as loneliness, depression, feeling scared and also denial. It's a good starting point posting here and asking for help, its quite isolating having to work this out on your own
Getting some help would a good start, can you speak to your team about getting some support ?
Ideally testing before each mealtime is advisable so you know what your levels are, if you need to take a correction and how much insulin to take for your food, it will be second nature if you can do this.
There's always someone on here for support so feel free to let us know if you need some help
