Practice with patients

I'm at 4th yeart of Psychology, and the next year I will have to do my professional practice. I will be Child and Adolescent psychologist. This semester I have a signature when I have to work in a pre-practice with a little girl, from a kindergarten of Ñuñoa. Her name is Gabriela, and she has 3 years old  (is a baby!!) . The work has been beautiful, but very difficult because she has little problems with languaje and pronuntiation of some letters, so sometimes, It has been very difficult understand us ( Its normal for her age, because she still are in languaje learning process). My wortk basically consist in do a psycodiagnosis because she show disrruptive behaviours and social isolation. I have been work with her since april, and this month, the process ends. The final diagnosis has relation with symptoms related to a Pervasive Developmental Disorder, because she was a little problems with her social development, but this are symtoms that has to be evaluated more deeply by a psychiatrist. This is my first "patient" in my life like a psychology student and future psychologist, so it has been an interesting experience, but full of insecurities as well, because its a big responsibility. ( She always talks about her favorite movie " Toy Story" ... in her english:  "tory tory" )
