Unfortunately your attitude is not a healthy one. You are judging your parents without even knowing why they sent you to the school that they did. In addition you feel that everyone around you needs to be exactly like you in order to succeed. What will you do when you change schools and realize that people over there sin as well. If I am not mistaken Reb nosson zvi finkel zt’l went to a coed yeshivah high school and still became Reb Nosson Tzvi. If you want to change yeshivas speak with your parents and explain your reasons. Most importantly be proud of your parents- your father is a Rav in a shul- he is helping saving the Jewish people.
If you focus on yourself and not on others life will be easier in your new school when you realize that all yidden have nisyonos they just come in different strokes for different folks. Hatzlacha.
