Very few people begin their search for an authentic way to live their lives confident and sure. Gender identification is deeply personal, and if you question your gender you most likely question most things about your life. The advice to talk to someone is a good one. I spent a long time in stealth research, and didn't discover as much about what makes me tick as I did in an hour of guided conversation. It is important that you really understand the parameters of your situation.
To decide to transition is breath takingly life changing. There are many here that I have a lot of respect for who have found a middle way of partial transition or adoption of true androgyny. That is not my story, but considering the commitment you are discussing, something worth exploring. Regardless a therapist can help you sort out your emotions, how you identify, and what level of dysphoria you are dealing with.
But do something, gender dysphoria can be life threatening. Too many of us slip away. There is joy and power here, but also sadness and grief. I hope you find the sunshine.
Good luck, you are in the right place,
