About 2 days ago, due to the extremely hot weather, I couldn't sleep thatduring the night.

And also by struggling in bed for hours, it's been a long timeI spent a long time in bed since I was struggling to sleep.

Had to guess a bit at the meaning of this sentence.

Yeah I wasSo, I decided to do my work until 6-7pm, then I sleep until 1pm.

"Yeah" as an interjection is kind of emphasising what was previously said, but you're talking about outcomes here so it doesn't quite fit.

That was one of my most productivitye nights, even though I was so tired but unable to sleep.

I got've had many issues with my health recently, but because I'm poor.,

Nthere's nothing I can do about that.

And also byI've struggling in bed for hours, it's been a long time.

Yeah I wasI decided to do my work until 6-7pm, then I sleep until 1pm.

That was one of my most productivitye nights, even though I was sovery tired but unable to sleep.

I got many issues with my health recently, but because I'm poor.

Nothing I can't do anything about that.

And also byI was struggling in bed for hours, it's been a long time was long.

A way to reword this if you are describing being in bed for a long time, unable to sleep.

Yeah I wasI decided to do my work until 6-7 or 7 pm, then I sleep until 1 pm.

We throw "yeahs" and "likes" into candid oral speech or during chats, but it should be avoided when writing out a post.

Just a comment, you wrote pm twice here, meaning you wanted to go to sleep at 7 pm and wake up at 1 pm (a sleep of 18 hours). Maybe you meant work until 7 am.

That was one of my most productivity nights, even though I was soreally tired but unable to sleep.

Any phrase with "one of X", X is going to be plural

I have (got) many issues with my health recently, but it's because I'm poor.

"Got" is optional here but "have" is obligatory

NThere's nothing I can do about that.

One Night Without SleepA Sleepless Night

Whilst your title makes sense, "One Night" sounds a bit clumsy. Instead, "A Sleepless Night" directly describes the night you are referring to and sounds more natural.

About 2 days ago, I couldn't sleep due to the extremely hot weather, I couldn't sleep that night.

By rearranging the sentence you can omit unnecessary commas and make the flow more natural. Also, you don't need to say "that night".

And also byIn fact, I was struggling in bed for hours, it's been a long time.

"it's been a long time" is redundant if you've already noted the duration. To introduce a fact to the reader, you can use phrases like 'In fact'.

Yeah I was I decided to do my work until 6-7pm, then I sleept until 1pm.

'decided' is already past tense, so no need to add 'was'.

That was one of my most productivitye nights, even though I was so tired, but unable to sleep.

if you use the grammar pattern 'one of (my/the,etc.) ... Nouns ...', the Noun must be plural (night --> nights). For example, "That was one of the best movies I've ever seen!"

I got many issueRecently I've had many problems with my health recently, but because I'm poor, there is nothing I can do.

Connect the last sentence to this one.

Nothing I can do about that.---

Connect with the 'because' clause so you explain the reason.
