I feel like I rely on my mom a lot too. I'm trying very hard to learn how to be more independent by taking care of myself and doing more things like driving places on my own, extra housework to help out as much as I can, and working very hard on becoming 100% being financially independent soon. I really feel like I trust my mom more than anybody in the world. She is also the only person who has been a constant in my life whereas other people have entered and then left my life while my mother has always looked out for me and been there for me. She's not perfect by any means and has her own struggles but I know she wants what's best for me. It sounds like your mom does too.
I can understand you wanting your mom to help with a work situation like that. The fact that you have a job though shows that you do have motivation to care for yourself. You said you also do your own chores which is great and you don't expect your mom to clean up after you which shows maturity. I know with the crisis that the shops are somewhat hectic and overwhelming so I don't blame you one bit for not wanting to go there. It's fantastic though that you are close with your mom though and I don't see anything wrong with what you are doing. Everybody needs help sometimes and it sounds to me like your mother is a good person to assist you when you need it.
Also, a lot of young adults live at home. My mom didn't move out of her parents' home until she was 34 and married. It's a pretty normal thing from what I've seen. I live with my family still and I'm in my 20's and many of my friends still do too.
