Many of us have had similar questions. Doubts are normal. Folk expect us to perform the role that they are used to seeing. Transitioning will change how folk view you and how you view yourself. This is a selfish act, but for many of us transitioning is also a necessary act. Dysphoria is masked by hrt. Stop hrt and voila, dysphoria returns.
Life involves many compromises and many difficult decisions. Only you, working with your therapist, can determine what your identity us, to accept this and to choose how you wish to live your life. There is no wrong or right answer, only your answer.
Safe travels
