Hi Merrick You are not an impostor. You are living your life as yourself. That is what matters more than anything else.
Impostor syndrome can be persistent. Even when others see you clearly and accept you, that inner voice sometimes still says you are faking it. But you are not. You are not pretending, you are not acting and you are doing what feels right and real to you and that is what counts.
You said you have been the boy next door and the manly man for a decade. That is not some performance. That is your life. That is how you are known and how you live. If you ever feel like improving yourself and it brings you happiness, then absolutely go ahead. But not because you think you have to prove anything.
For me, when I changed my life, I never felt like I was acting. My personality never changed. I was just living and carrying on as me. It was not some kind of show. It was just simply life. Nothing less and nothing more. That is how I see what you are doing too.
As someone else said above, one reason impostor syndrome can take hold is the belief that there is some fixed standard to meet. But there is no such target. The only target is what your dreams are and how you change your life to meet those dreams. You do not need to match anyone else's pattern or lifestyle to be real. You already are.
If these feelings continue to trouble you, then yes, speaking with a therapist who understands gender-related issues might help. It is not about fixing anything. It is about exploring the roots of that doubt and finding a way to quiet it.
Just be yourself. You are not a faker. You are not a fraud. You are a person living the life that makes sense to you. That is enough. Keep going. Keep being you.
