Getting ready for insulin

So my diabetes Dr said I have two weeks to try a bedtime snacks protion,fiber or no snack maybe and see if any of the above bring my fasting number down. It's the end of week one and no snack has brought my fasting number down 😒. So I'm preparing myself to be put on bedtime insulin. I would just like to say I'm terrified of giving myself a needle! Is there any way to prepare myself..I don't no how to give myself needles!
