A warm welcome to the forum.
Yes it is hard getting use to injecting, especially when you have a fear of needles. I learnt to inject in hospital as I was admitted at the time of diagnosis, the diabetes team and ward staff wouldn't let me go home until I was confident at doing the injections, had to practice the technique on a orange.
See if there's anything in the following which might help you:

same as @noblehead and @Robinredbreast for me -- lots of practise on an orange in hospital.
