This reminds me of that nirvana song come as you are, but i think you should state you facts and if your grown enough to make that choice then so be it, just respect there personal boundary's and they must respect yours no matter the conditions. its your body and before you know it you be on your way to you life and they should except it how it is, so yes I think you should, the best thing you can do is be very open and tell the truth on how you feel and how much this choice means to you and with out them it wont be what you want, cuz all you want is parent support. its not them so what they think you CAN NOT let that affect who you are striving to be...I wish you the best of luck.😊
