recent diagnosis

Hi i am 26 and my partner was last week diagnosed with adhd after struggling with it his whole life. His relationship with his mother has also broken down. I am so relieved to be on the way for him to be getting help but i think i need help myself. I know he cant help leaving the lid off the milk, being extremely messy, stressed,angry and all the other adhd traits which drive me around the bend. We have been together for three years but i still nag at him or should i say niggle at all the little details he misses like leaving drawers open and not wiping the side down when he has messily made a drink of tea. I constantly try to bite my lip but i struggle doing so and really need advice on this. I just don't know what to do and i don't want to put extra strain on the relationship when we have come so far already xx
