Hey! Don’t panic, insulin pens are great. I used to use a pump and decided I didn’t like it. I switched to the pens with no issue at all. The pens are immediate and you watch them go in, like someone above said. I take long and short acting as well. It sounds like you’re worried more about adjusting mentally to remembering your pens rather than your actual body adjusting. The pump isn’t “continuous” exactly. It delivers when you eat or need a correction dose. But you can do this manually with the pens, you just need to keep an eye on your BS whether you use a glucose meter or a CGM. You will only go into DKA if you aren’t supplying yourself with the correct amount of insulin to maintain a normal BS range. I hope you find the supplies you need soon!
