Nonetheless, I continued going everywhere and trying to show everythingshowing all the interesting places to my guests.

But, after three days, I found myself in the hospital receiving some medicines into the veiintravenous medication.

Colloquially, we just say "I found myself in the hospital getting an i.v."

However, the situation was far from starting to get wellbetter.

Nevertheless, the guests and everyone were very attentive, and, after taking antibiotics and some antivirals, I started to recover from it after three weeks.

The comma is optional here.

I think that the time that the visitors were over my place was not as bad as minee visitors had a better time here than I did, therefore I believe they could get to know and enjoy the city.

We live very far from our hometown and we had the immense surprise tof haveing visitors over during Christmas.

It started with nauseas and general discomfort.

Nonetheless, I continued going everywhere and tryingdoing my best to show everything interesting to my guests.

The phrase "everything interesting" isn't quite natural although it's grammatically correct. You could say something like "doing my best to entertain my guests", or "doing my best to show interesting things to my guests" and it might sound a little better.

"Hooked up to an IV" is a common US idiom for this scenario. IV stands for intravenous.

Day 1 - Christmas Sickness ;)

We live very far from our hometown, and we had the immense surprise tof haveing visitors over during Christmas.

Unfortunately, after a few days of having guests at our home, I started to feel very sick.

It started with nauseas and general discomfort.

Nonetheless, I continued going everywhere and trying to showwith my guests and showing them everything interesting to my guestsaround.

I am using the phrase "show around," as in to introduce someone to things in the area.

But, after three days, I found myself in the hospital receiving some medicines into themy veins.

However, the situation was far from starting to get wellbetter.

I think that the time that the visitors werehad over at my place was not as bad as mine, thereforethe time I had, so I believe they could gegot to know and enjoy the city a lot.

"A lot" just makes it more natural sounding, but isn't necessary.

Day 1 - Sick on Christmas

We live very far from our hometown and we had the immense, so we were really surprised to have visitors over duringfor Christmas.

The grammar in your original sentence is perfect, but your wording sounded a little unnatural. Another corrector gave you a good example of more natural phrasing, I'm just providing another one :)

It started with nauseas and general discomfort.

Nonetheless, I continue going everywhere and trying to show everything interesting to my guestskept going out with the group and trying to show my guests all the interesting sights around town.

You could also say "trying to show my guests around"--"showing someone around" means showing them the important or interesting aspects of a place.

But, after three days, I found myself in the hospital receiving some medicines into the vein.hooked up to an IV.

I suggested a more natural way to convey your idea.

However, the situation was far from starting to get well.Despite the medicine they gave me, my recovery was far from over.

I tried to guess what you might have meant and suggested a clearer/more natural phrasing.

Nevertheless, themy guests and everyonefamily were very attentive and, after taking antibiotics and some antivirals, I started to recover from it after three weeks.

Note: "I started to recover after three weeks" means your symptoms only started to improve once three weeks had passed. If you started to feel better before that (which I hope you did!), you could say "I slowly recovered over the next three weeks" or "I was fully recovered after three weeks".

I think that the time that the visitors were over my place was not as bad as mine, therefore I believe they could get to know and enjoy the city.certainly think my visitors had a better experience over Christmas than I did, so hopefully they got to know and enjoy the city enough to come back in the future.

Again, your grammar is perfect--your phrasing is just a little unnatural and the main idea you're trying to communicate isn't super clear to me. I took a guess at your meaning and the tone you were going for (slightly humorous, maybe?) and suggested more natural and specific wording.

Day 1 - Sick During Christmas Sick ;)

We live very far from our hometown and we had the immense surprise to, so it was a big surprise when we found out that we were haveing visitors over duringfor Christmas.

The way I wrote it sounds more natural. "we had the immense surprise" is not natural sounding. It's better to say "big surprise".

It started with nauseas and general discomfort.

Better would be "receiving medicine from an IV" an IV is a device to gives you medicine via your veins.

This okay, but awkward. Consider: I don't think my visitors had as bad a time as me, so I believe they got to know and enjoy the city.
