I really wish I can be a girl
Do you genuinely feel that way? Do you feel like it is a gender thing?
Yes, I feel more comfortable in a female form.
If you truly feel like you should be a girl, that is a brave step to take. Hopefully, you can be on the path to being your true self.
The truth is that I'm bi and a half.
If you're feeling like a different identity than what you are now, I believe it's a good choice to consider transitioning after the proper mental check ups. You deserve to live the rest of your life out in the form you most desire, and it's great you can express such things.
