Hello Sarah and welcome 🙂
I'm needle-phobic too and I'd be completely and utterly unable to inject myself with needles I could see. I use the Autocover ones in Matt's link and they make it easy, it's just like pressing the end of a pen against your leg, you don't need to see the needles at all. The only downside with the Autocover ones is they are slightly longer than the standard needles for diabetics - I think there are other makes of covered ones which are shorter - but we're talking mms here, so it makes very little difference. In fact I now find injecting myself so easy I sometimes choose to have an extra injection, if I want a snack or something!
Definitely turn down the finger pricker! You should barely feel it and it shouldn't leave bruises. I have mine set to 2. It sometimes takes a few goes to get it to work, if my hands are cold, but that's much better than having it turned up more! And only ever use the sides of your finger tips, there are nerve endings in the front of your finger tips so it will really hurt if you prick there. Also, you may have been told to only use your middle two fingers, but most of us forget that and use all our fingers and thumbs as well, in turn. So long as you only use the sides it shouldn't matter (it might if you use the fronts, which is why they tend to tell you just to use the middle ones).
