@Lolly Firstly, welcome to ShootUp.
I’m not sure from your post whether you’re still on beef insulin or whether you moved off that when you changed to pens? If you did, I wonder whether the switch to human insulin is causing some of your problems – this isn’t uncommon. IDDT are the gurus when it comes to switching between human and animal insulin – if you have switched, it might be worth having a read of their site to see if you think any of your issues have been caused by that.http://www.iddt.org/
The other thing is remember this is your decision. If you aren’t happy and you believe that your previous regime was best for you (and that the problems were caused by stress, not the actual treatment) tell your team and be clear with them about what you want.
