Hi,Grown-up,
As a student of your age, I understand your situation. The problem you are facing is common among our teenagers. However, it should be wise not to do anything that may hurt her feelings. Here are a few suggestions.

First, it's advisable to talk more with your mom. I learnt talks help you understand each other better. They are also opportunities to let her know your ideas of and attitudes toward many things.

Second, you should learn to do your own things well, proving to your mom that you are already a “grown-up”, It's even better if you could share more of the housework, such as cleaning, washing and cooking.
