Don’t let their dissaproval of you be a reason for you to dim your light! Continue to shine bright and follow your own bliss. Let them disapprove of you, let them have their opinions – that is a reflection of their character, not of you.
Be the beautiful, unique being you desire to be, allow yourself to blossom and live the happy life you want to live. If it feels good to you and if it brings you joy, then you are following your bliss and only good can come from that.
