Welcome
@OLVE75
I remember those early days when diabetes was such a pain and a drag and felt as if it was taking over my life.
Thankfully, I had a wonderful DSN who is still with me 20 years later who explained that diabetes should not stop me doing what I want. I have pushed it quite a few times with travel and food and exercise and drinking and more. But, she was right, it has never stopped me.
However, that is because I kept taking my insulin. If you stop the insulin, diabetes will affect your life a lot more than a bit of preplanning for drinks or food.
Whilst injecting insulin maybe an inconvenience, it should not be painful. Some people find that some insulins can sting but there are plenty of varieties of insulin available that you should be able to find one (or two) that do not sting.
Please talk to your Diabetes nurse as soon as possible (mine responds to emails), explain how you feel and the pain that insulin is causing.
I am not sure why you have been told to eat regularly as long as you take your insulin when you eat.
In the olden days (before I was diagnosed ... so a long time ago), it was important to keep to a strict regiment for eating but the wonderful thing about the fast acting insulin (Trurapi ... and others) is that you can eat when you want. And not eat if you don't want to.
Type 1 is managed with insulin, not diet. It is as important to eat a healthy diet with Type 1 as it is if you don't have diabetes.
