That’s part I understand. What I don’t understand is

a role that does not reflect who you are

how you see yourself and how you want to be.

In the context of gender, where do these feelings come from? How do I know if a role does or doesn’t reflect “who I am?” Where does how I see myself come from and where does the desire to be how I want to be come from?

You haven’t actually answered my question, sorry to say. What I’m asking is where does the feeling of being “forced into a role” come from? How do I know the role is not right for me?
