In fan fiction, Thor's suicide attempt could be due to his isolation. He's a god, and being a god can be a very lonely existence. He may not feel like he belongs anywhere, not fully in Asgard anymore and not entirely on Earth either. This sense of not having a true home could push him to such a dark thought.
Well, it could be driven by his sense of guilt. Thor might feel guilty for not being able to prevent Ragnarok completely, or for not saving more of his people. This guilt could eat at him to the point where he contemplates suicide.
Another factor could be his loss of purpose. Thor has always had a clear mission, whether it was to protect Asgard or the Nine Realms. But if that purpose is suddenly taken away, like if Asgard is destroyed and there's no clear way to rebuild it or his role in the new order is uncertain, he might feel so lost that he considers ending his life.
