I to am on a lot of meds including antidepressants meds, when l was told l needed to start on insulin. I imagined constantly injecting and l was afraid. When l started l was amazed that often finger pricking hurt more. It's easy to change how many units l gave myself , if going out and my testing blood glucose was a bit high l gave myself just a few more units to compensate which you can't do that with oral meds. I am sure many could give you a lot more info. Don't be afraid
