All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
You did not mention why it is difficult for you to change your academic path and study at another college (even if a non-scientific one). We believe that if you think with deliberation about the consequences of dropping out of college altogether, this will enable you to endure the difficulty of starting at another non-scientific college.
Anyway, you are not left with two choices only, either to carry on with studying medicine, or drop out of college. There is a third, better, and more beneficial option, which guarantees your happiness in the worldly life and Hereafter, namely, to devote yourself to the memorization of the Quran, studying Tafseer, and then learning Islamic studies. Please refer to Fatwa 15872 in this regard.
This third choice needs seeking the help of Allah, The Exalted, and having a firm resolve and unrelenting determination while paying no attention to the discouraging remarks of people who fail to realize the honor of the one who has memorized the Quran and the virtue of studying Hadeeth and Islamic studies in general. We also advise you to hasten to marriage, as perhaps Allah, The Exalted, would bless you with a husband, with whose religiosity and moral character you are content who would help you remember Allah, express gratitude to Him, and worship Him as due.
Allah Knows best.
