Please talk to somebody . I know it ' s tough right now , I know you ' re in pain . But at least let someone in , tell someone how you ' re feeling . <| sep |> Regardless of brain maturity the truth is no matter what your age is you will be a different person throughout your life . If you take someone that is say 60 years old they were a different person mentally when they were 30 , different when they were 40 , 50 etc . It may be subtle differences but my point is the mind is constantly molding itself throughout life no matter how old you are . These mental states and changes continue to occur even after you reach an age where the brain has stopped growing physically . IMO the development argument is kind of BS . I could see why someone would question the thoughts of say a 5 year old but once someone is even at the age of like 13 they have had the ability to think critically for awhile at this age . I pretty much questioned myself and started seeing myself as a girl at the age of 9 or so . As the years went by the feeling only got stronger . Prior to 9 I didn ' t really understand the differences too much between genders but even with that being said I would still secretly dress up in my sisters clothes . I remember being 4 years old dressing up , but at that time I didn ' t understand why I enjoyed it although I understand now . I also think that it kind of goes on an individual basis . Not everyone will develop the same way or speed and not everyone will feel the same at certain ages . It really comes down to an individual basis .
