Is my faith slipping away?

Assalamu alaikum. I've been a Muslim my whole life, and I regularly read the Qur'an. But lately, studying science and diving into endless arguments online is making my head spin. The thought that Allah might not be real honestly terrifies me, and I want to hold onto my deen. Yet, juggling uni all week and then opening the Qur'an just feels overwhelming. I don't want to lose my iman or become a disbeliever-this fear is eating me up. I'm so scared. How is this happening to me?
