My daughter's pump tries to keep her at 6.2, which is a perfectly healthy number right in the middle of the range, maybe try that for a while and see if you feel better? Finding the right balance can be hard, when my daughter was first diagnosed I tried to keep her with perfect numbers all the time and would get very frustrated when she got a high one for no obvious reason. But it's not possible to keep it perfect all the time, anyone who claims you can is being a bit economical with the truth. It took me quite a while to learn to relax a bit and accept that some days will be less than perfect, as long as you are not ignoring the situation and are making an effort to keep things reasonably well controlled (I.e. not sitting at either extreme for hours at a time) then you're doing ok. I always remember our DSN saying “there's no point spending the whole time trying to get perfect numbers if that's all you do, you have to enjoy life too”. That helped me a lot!
