Struggling with helping around home

As the title says. I'm 19F, living with my boyfriend and his parents and little sister. I'm struggling with depression and anxiety since I was 14. My boyfriend just asked me to clean the kitchen, and I just feel so guilty about not helping enough, not cleaning from my own will. I want to, but everything feels like huge task. I'm in the bathroom crying (lol). I'm too anxious to face my boyfriend, when he'll know I cried, he always does. Idk what to say, I can't really talk about my feelings. My boyfriend is so sweet and loving, understanding. I just wanted to get it off of my chest. I feel like a child, crying over such a stupid thing.
