Diabetes is a full time illness and most people find it hard sometimes (I certainly do). That's not your fault and there should be no shame in admitting that you are having a difficult time.
You've taken the first step by posting on a diabetes forum for help. We're slightly limited on what we can say (no specific dosing advice) but many folk here have been in your position and we can give you moral support and maybe some tips.
Can I ask what pump you are using? (I'm on a tandem and while it automates a lot for me I still have to manually input my basal rates, which can change over time.)
Are you able to contact your pump clinic for advice? They will be very used to diabetics with burn out and should be able to help you with some of your issues. If you aren't confident to make pump adjustments yourself then they are your first port of call, though we can give you links to basal rate testing, if that helps.
Once more welcome. We are here to listen to you.
