Plagued by uncomfortable doubts about Islam

Salaam I have recently been overcome with doubts about Islam. These doubts aren't logic related and I hate them. It is clear to me that the Qur'an is from Allah, however a disturbing thought keeps popping up like what if some other human wrote the Qur'an which I don't believe but the what if keeps popping up and I feel far from the deen. Please can you provide me with resoning and Quranic miracles for me to resolve this with whenever it pops up? Please make duaa for me JazakAllah
