Need help with past tenses

[Silversky]

Hello, newcomer here and obviously not a native English speaker.

So, short introduction, I'm trying to write a story in English. Thing is, even until today, I may have some difficulties applying grammar basics, understand them, and get used to them.

Now, to the question, I have this paragraph.

--
The doctors at the hospital thought that Rolf suffered from some kind of neurological problem. The exact diagnosis, however, was uncertain. The fainting before wasn't caused by dehydration as what Rolf's mother thought. But Rolf's condition looked healthy, so Rolf asked to let him get discharged from the hospital. The doctors denied the discharge request as they're still trying to diagnose for the fainting and the memory loss. Rolf then gave the doctors 2 weeks to find something if they think that there is something wrong with him.
--
(Do tell me if you need me to explain further of what's going on with the story, even I have difficulties understanding that.)

The paragraph is supposedly to be in something like a biography or past history, but my past tense understanding is a real mess. So I'd be glad if someone can guide me on how to fix the grammars and maybe even the whole paragraph if you will.

Oh, it's purely my hobby, not assignments/homework/such.

Thank you.

Hello Silversky, and welcome to the forum.

What does the underlined part mean? If you wrote the story, how can you not know what's going on?
