Hi,Gown-up.
I can understand your feelings for you are almost an adult and you want to be independent and get rid of your mother's management.But,you should understand your mother for what she say and so are all care about you,you should be happy about it at first.However,sometimes you may be tired of it,so you should take measures to solve the problem.
In my opinion,you must rely on your mother a lot which causes the problem.Therefore,you should do something to prove that you have already grown up like washing your clothes,socks and so on.In all,you should show your life common sense to your mother.
At last,I hope that you can be successful.
希望能帮上你喔！！
