Hello Elsie,
Try not to be despondent,I have had times when I have felt totally overwhelmed with this confusing,scary illness,I still cannot get to grips with how the dosing (too little or too much insulin) works.
Please don't stop posting,let these amazing knowledgable people guide you,the more they do, the more you will understand how to look after Max.As we say in the UK keep you chin up,hope you have a more peaceful day today.Diane & Bailey
