This Monday, I started to feel uncomfortable, and came up with some symptoms like a sore throat and running nose.

At first, I thought this iwas just a normal cold because I've haven't been not wearing a shorts or drying my hair after showering recently.

But things got worsen on the next day; I decided to do a rapid test forto makinge sure whether it' was Covid or not.

Or "things *worsened* the next day"

Not surprisingly, two solid lines appeared within 5 minutes after I dropped my sample on the rapid test.

It's not my first time to be infected by Covid, but it's been over a year from last time, so I guess the antibodyies inside me isare not enough to fight back the virus.

Or "the antibodies inside me *aren't* enough"

I went to the doctor right after knowing the result, a. As usual, doctor only asked some questions about my symptoms and giave me medicine for a three-days treatment.

It's not unexpected that I'll geot Covid since some relatives visited us a few days before I started to feel sick, and t. They have almost the identical symptoms as mine.

In conclusion, Covid is still existing,s, it just noisn't that extensive like before.

Make sure to use alcohol stillstill use hand sanitizer to disinfect and wash hands every time whenyou arrive at home or before eating.

It's more common to say hand sanitizer than alcohol, but what you said is understandable.

I'm getting way better now, but I'm not fully recovered.

I still cough occasionally, i. It's better to drink enough warm water to keep the throat moist and not overuse it.

What you wrote in the second sentence sounds like advice for someone else. If you meant to talk about yourself and what *you* need right now, use "It's better *for me* to drink enough warm water to keep my throat moist and not overuse it."
If it is advice for other people, I think that sentence should go next to the one about hand sanitizer.

GotI got/contracted Covid again.

In more informal language and casual talk, "got Covid again" is ok. However, it is still missing the pronoun (in this case I) and isn't grammatically correct.

This Monday, I started to feel uncomfortable, came up with s. Some symptoms came up like a sore throat and running nose.

Make sure to not overextend sentences too much. The sentence is best ended at uncomfortable. After prepositions such as "This Monday", only one subject and verb pair can fit usually. This is a common issue for native English speakers, so don't worry too much about it if it takes time to get used to! "Came up with some symptoms" is an awkward way to phrase the sentence as the meaning of the sentence because the subject becomes unclear; you would want to put the subject "some symptoms" first assuming you were referring to your symptoms coming up. Sore throat is usually spaced out into two words.

At first, I thought this iit was just a normal cold because I've not been not wearing a shorts or drying my hair after showering recently.

Usually "it" is used instead of "this". Shorts when referring to pants is almost always in plural.

But things got worsen on the next day; I decided to do a rapid test forin order to makinge sure whether it'my illness Covid or not.

Worsen is used only in very specific constructions. I would recommend putting it off for later. You're referring to a past event, so use the past tense "decided" instead of the present "decide". "Whether it's Covid or not"'s subject is vague so I would directly name the subject.

It's not my first time to be infected by Covid, but it's been over a year from last time, s. So I guess the antibody inside me is not enough to fight back the virusmy immune system is vulnerable/weak/susceptible to infection.

This sentence is another that is too long. Beginning with so, a new sentence should begin. Antibodies are rarely referenced outside of academic settings when referring to immune health, so I would refer to immune system. Lastly, simply your sentence by attaching an adjective to your immune system; the implied consequences of a weak immune system is sufficient.

I went to the doctor right after knowreceiving the result, as. As usual, the doctor only asked me some questions about my symptoms and giave me medicine for a three-days treatment.

This is relatively ok. Just keep working on appropriate tense usage. When questions are being asked, the subject should be identified. Time periods don't use the plural such as in "five year plan" or "9 month time frame".

It's not unexpected that I'll geot Covid since some relatives visited us a few days before I started to feel sick, and t. They haved almost the identical symptoms as mine.

" I'll " is future tense being described in the past. I would keep on practicing tenses. And doesn't describe clear causation and over extends the sentence so a step in the right direction would be to start a new sentence.

In conclusion, Covid is still existing,s. It just noisn't that extensive like before.

Though Covid still exists right now, it is not appropriate to describe it as "existing". Rather, it is better to use exists.

Make sure to use alcohol still to disinfect andsoap and water/hand sanitizer and make sure to wash hands every time when you arrive at home or before you eating.

I think you are describing hand sanitizer when mentioning "alcohol". People don't refer to hand sanitizer as alcohol usually. "Make sure" gets lost in longer sentences such as these, repeating "make sure" makes your sentence clearer. When giving advice, it is best to identity the action you want the other person to take throughout to make your point clear.

I'm getting way better now, but I am not fully recovered yet.

You will want to keep using pronouns even when it has already been identified earlier in a sentence. Not adding yet to the end of the sentence makes the illness take a more permanent tone, which usually isn't the case with Covid.

I still cough occasionally, i. It's better to drink enough warm water to keep the throat moist and not overuse it.

The comma describes relation between the two parts of this sentence when they are not closely related. Therefore, I would separate them into two different sentences. The second part of the sentence is phrased like advice and might make more sense in the advice portion of your journal.

GI got Covid again.

But things got worsen on the next day; I decided to do a rapid test for making surto determine whether it's Covid or not.

"Whether" already means "if something is or if it's not". No need to put "or not" after "whether".

Not Unsurprisingly, two solid lines appeared within 5 minutes after I dropped my sample onto the rapid test.

It's not my first time to bebeing infected by Covid, but it's been over a year fromafter the last time, so I guess the antibodyies inside me isare not enough to fight backagainst the virus.
