First of all understand that above all things your mom loves you. You are her flesh and it scares her to see you grow up. She does not know how to react to this change of maturity that she sees in you. She does not know how to respond to the fact that you are growing up and because of this fear turned into anger. The anger caused her to think that if you believed that you were grown up then you must be ready to confront the world on your own. This is something mothers do because they resent the fact that you are growing up. Realize that this is simply fear. She does not hate you , she loves you and she cares for you no matter what she says. Communicate with her let her know that you do not hate her and that you simply feel that you are growing up therefore you feel the need to be responsible for your own things and that that does not mean that you do not love her or that you dont need her anymore. Also realize that growing up does not mean that we no longer depend on our parents, we will always need the support from our parents. They are the only ones who will always stay true to us. Talk to your mother and do not do things that you will later regret.
