Should she continue her studies in a mixed school where there are no Muslims?
Question

                Recently I have turned back to my deen, Alhamdulilah, and I have a few questions regarding how I should conduct myself in my mixed western school. I've been in my 11th year for a few months now and have started this year with tremendous change. I wear hijab and abaya now, I don't go out or "chill", I don't free mix if I can help it, but many times its inevitable.There are barely any muslims in my school, and of the few hardly any practicing so there is basically no righteous company to be among. I would hate to isolate myself and be an outcast among people, and ignore the friends I have had previously, less they think Islam is a suppressive and has made me antisocial and introverted, especially since they have been understanding and accepting of the changes I have made. How should I interact with them? How do I stay concious of Allah in an environment filled with so much nonsense and peer-pressure and haram? I don't enjoy learning in this environment where teacher's and student's friendships trandscend gender and age, and there is no shame in broaching indecent or modest subject matter in classes, but I cannnot afford Islamic schooling. There is another public highschool nearby however that is more diverse and with more muslims although many again are not practicing. Should I try to go there instead or be patient in my circumstances?.
Praise be to Allah.
      Firstly: 

    We praise Allah, may He be exalted, for having enabled you to 
    adhere to hijaab and we ask Him to increase you in guidance and 
    steadfastness in following the truth. 

    Secondly: 

    Mixing between men and women in schools, workplaces and so on 
    involves many risks and evils, and its negative and harmful consequences are 
    clear and cannot be denied, even in Western countries themselves. 

    Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) 
    said: 

    When men mix with women, it is like mixing fire and wood. End 
    quote from al-Istiqaamah, 1/361

    The danger is worse in the school where you are studying 
    because there are no Muslims there. 

    Based on that, it is not permissible for you to carry on 
    studying in this school, and if you have a permissible means of learning 
    that does not involve mixing, such as online learning and so on, this is 
    what you have to do. If that is not easily available, then you should move 
    to another school where there are Muslims; this is less bad than where you 
    are now. 

    You have to avoid mixing with men/boys and speaking to them 
    as much as possible, and let your friends only be Muslim girls. For more 
    information please see the answers to questions no.

    With regard to your saying “how should I interact with my 
    male friends and female friends?” 

    With regard to your male classmates, it is not permissible 
    for you take them as friends. 

    With regard to your female friends, you have stated that they 
    are not Muslim. The Prophet (blessings and peace of Allah be upon him) urged 
    us to make good choices of friends and choose those who are religiously 
    committed and of good character, because a person will be influenced by his 
    friend and will imitate him. And the Messenger of Allah (blessings and peace 
    of Allah be upon him) said: “A man will follow the religion of his close 
    friend, so let each of you look to who he takes a close friend.” Narrated by 
    Ahmad. 7968; classed as saheeh by al-Albaani in Silsilat al-Ahaadeeth 
    al-Saheehah, 927 

    It says in Tuhfat al-Ahwadhi: i.e., a person will 
    follow the habits, way and behaviour of his friend, so let him think long 
    and hard about who he takes as a friend; if someone's religious commitment 
    and character are good, then take him as a friend, otherwise avoid him, 
    because the behaviour of your friends will influence you and the company you 
    keep has an impact, be it positive or negative 

    With regard to your saying that you do not want the people 
    around you to have a bad impression of Islam and Muslims, and think that 
    Muslims are antisocial and did not like to meet their friends, especially 
    when they have been accepting of these changes you have made your life: 

    Islam does not tell Muslim to keep away from people and not 
    have any friends; rather it enjoins us to keep away from evil and to avoid 
    places of temptation, and to keep away from people who may cause you to 
    disobey Allah. 

    What is required of the Muslim is to adhere to the rulings of 
    sharee‘ah and give a good impression of Islam to non-Muslims, by showing 
    them that Islam is a religion of chastity, modesty and good morals, and that 
    it does not permit its followers to follow whims and desires and 
    temptations. Islam forbids immorality and evil, which includes free mixing 
    between men and women, as mentioned above. 

    We ask Allah to guide you to that which is good for you in 
    this world and in the Hereafter. 

    And Allah knows best.
