Hey Anna,
I totally know what you are going through. For the first month after I was diagnosed with diabetes I was totally frozen when I tried to give myself a shot. Ask your doctor about a little plastic divise which gives the shot for you (I'm not sure what it's called but I'll do some research) but it's this little plastic gun looking thing, where you load the needle and press a button and a spring shoots the needle into your skin. You don't see it go in, and you hardly feel it, you just have to press a button. Like I said I'm not sure what it's called but I'll do some research for you, it totally saved me!!
