Hopefully, your therapist will help you fully come to terms with who you are. It takes time, but eventually you can actually believe that it's ok to be transgendered and can more confidently build your life to incorporate CDing. It need not be all consuming, just a part of who you are.
Your short term objective should be to achieve financial independence and a place of your own. That way you can either keep your CDing hidden from family or come out slowly and selectively on your own terms and timetable.
