Diary - I had a quite serious diarrhea

[Maybo]

This is an entry from my diary. Please check it and correct any mistakes.

I had a quite serious diarrhea on Monday night. While I was sleeping, I woken up by my painful belly. At first, I just wanted to ignore it and went on sleeping but something was off. Just a moment later, I felt the burst! I couldn't hold it and pooed four times until early morning. I didn't understand why but I suspected it was because I took antibiotics in May and the meds killed lots of good bacteria in my gut. Now I was still not strong enough to fight against very bad bacteria. My mum had similar food to me but she was all well. Fortunately, I didn't have fever.

I had a quite serious diarrhea on Monday night.

Diarrhea is not countable. Google "degrees of diarrhea" and see if you can find the right adjective. You can add the adjective "painful" to get your point across.

While I was sleeping, I woke [ 1] woken up in the middle of the night with a stomach ache. by my painful belly. At first, I just wanted to ignore it and went on sleeping tried to get back to sleep, but something was off. Just a moment later, I felt the burst! I couldn't hold it and pooed I had to rush to the toilet/loo four times that night. until early morning. I didn't understand why I had [ 2] the runs, but I suspected it was because I had taken [ 3] took antibiotics in May and that the meds killed lots of good bacteria in my gut, and that Now I was still not strong enough to fight against very off bad bacteria. [ 4] My mum had similar food to me earlier that day but she was all well. Fortunately, I didn't have a fever that night or on Tuesday morning; thank Goodness!

[ 1]: I'm sure I've told you before, but I'll say it again: Always go over your work before submitting it, to catch obvious/simple mistakes.
[ 2]: "the runs" is a colloquial/informal phrase meaning diarrhea.
[ 3]: Note the past perfect. You are talking about a past action "take antibiotics" that took place prior to another "have diarrhea".
[ 4]: Do you see how that sentence is disconnected from the previous part? Try inserting an appropriate linking word here.
