Unfortunately, the school was unable to provide an environment that encouraged learning.
Right after this, you can improve the credibility of the whole essay with a bit of explanation:
Unfortunately, the school was unable to provide an environment that encouraged learning; a lack of funding caused the typical school day to be _____________________, and the learning process was made dysfunctional by the __________________________ that characterized Bahrain in recent years.
:-)
The first part of the essay can be improved with this explanation, because the reader will know that it really was the school's inadequacy rather than your rebelliousness.
For the last half: Specify a few schools of thought in psych that resonate with you! Google around about existentialist psychology, cognitive psychology, psychoanalytic, etc., so that you can give at least one sentence about your plans as a psychologist. Good choice, by the way!
