Hi Natasha
Sorry to hear of your diagnosis of T1, but glad that you have found this forum.
What past experience of Diabetes do you have?
How was your T1 diagnosed?
If you were very poorly when diagnosed, which is quite common, you will no doubt feels a lot better now that you have some insulin in you. There is a lot to learn very quickly but it sounds as if you had a head start with some prior knowledge of the condition. It takes time to get your correct doses of background and basal insulin sorted at the start, so you will need to be patient with yourself and keep in contact with your specialist team, as they are there to help with this. At first a lot of people diagnosed with T1 have some beta cells still hanging around so things can be a bit unpredictable, as they start to pay again after a bit of a rest.
I know that a lot of people on here have found the book Type1 Diabetes in Children Adolescents and Young Adults by Ragnar Hanas a very useful reference. Ignore the age reference. I was 53 at diagnosis and still find the book helpful. It is well referenced and has very clear explanations throughout. It is also regularly updated with the latest technology, so well worth getting the latest edition.
You mention that you suffer from depression. It would be useful to mention this to your team as they may be able to give you access to specific support for those with Diabetes. If not talk to your GP. But above all remember that this condition is manageable, and there is plenty of support available from a variety of people on here. If you have any questions just ask. No questions are considered silly on here.
