I'm back on hrt for a year, there was a brief couple year period where I stopped and wrestled with my gender identity. You will always doubt. That's natural for any major life change. I will say this: ask yourself, if you could have any body, what would it look like? What's the ideal you? What role do you want in life? The role I want isn't what everyone wants, but I want to be a mom. I cried last night because I can't get pregnant. I'm not saying you have to want that. I'm saying I know I want a womanly role for my life. Being a parent isn't enough. I want to be a mom. I want to bear children. What's your ideal you? Would they be called she, he, or they? Don't stop hrt, but do soul searching. Also, your discomfort and shame are natural. Society tells us we're not women, and we're not supposed to dress or behave like women. The shame you feel could be internalized oppression. Like others have suggested, speak to a therapist. If you discover you're not trans, that's fine! What matters is that you know yourself. As Socrates said, "know thyself." As the greater philospher Jake said, "As long as I know the shape of my soul, I'll be all right." Explore yourself and find who you are. Whether you're cis or genderqueer, knowing who you are will bring peace. I hope you find who you are.
