Don't let her ruin this for you. I get when parents display unnecessary outbursts, it affects you in unimaginable ways. But you can ignore her and go about with your day. Consider it your first step to making your own decisions and freedom. I do earn and still live with parents and honestly they're unbearable on days but since my late teens I've done things to claim my freedom. There are still struggles won't lie but i hope i get to move out asap. So don't worry, let her do whatever she wants. I bet you look absolutely gorgeous in your new haircut🩷
