Sorting my Finances

Hi. Historically I have been bad with money matters - always going over budget, spending impulsively on food, etc. I have a budgeting spreadsheet but somehow I am still struggling with how to manage our finances. I am a housewife who does the groceries while my husband works for both of us. It is weird that someone like me who might have ADHD is managing groceries every month, but no one else can since my husband goes to work. Monthly my husband berates me for committing the same errors -- just today he got mad at me again for the same reason. He even said he does not know how to trust me do I go about fixing myself around money?
