At this very moment, I’m quitefeeling discouraged and desperate.

Sounds more natural.

It has nothing to do with what is going on in the world: the war in Ukraine,; the out of control increase in the cost of living as a consequence of the war in Ukraine, the current; the unstable political situation in my country,; the record high temperatures,; the 6th generation wildfires that are devastating our country as a result of, among other factors,; and the heat wave we’re enduring.

Removed current because it is implied and Ukraine because it was already mentioned. Made suggestions for brevity.

Generally, if you make a list with long phrases, separate them with ; instead of , .

Yesterday, I finished reading my last book and, as it always happenis, starting a new one ihas never been an easy task.

Alt: As always

The new book is easier to read than the previous one and that fact makes the reading be more enjoyable, more appealing, and more riveting.

Removed the 'more' for brevity, but either is fine.

“The Kind Worth Killing” is a page-turned;r -- the kind of book you start reading and can’t stop until you’ve finished it.

In a nut shell, although it took me to read it more than a month to read it, I read every day for over one hour, i. It was worthwhile reading.

“"The Kind Worth Killing”" is a thriller quite similar to another one I read six years ago: “ called "The Girl on the Train”."

A week earlier Ibefore finishing a book, I’m already thinking about the next one I’m going to read.

I hate to beginning a book and not be able to read it because of my level of English is not being high enough.

I also hate to spending endless hours looking up words in the dictionary.

By doing this, I lose the threatd of the plot.

This is why it is so important to pick out the right book.

Periods go inside quotations.

Like someone suggested that I dido, I pretended to write a review about “The Kind Worth Killing”," but as it usually happen to mes, one thing leads to another and at the end, I’ve writoten about something completely different.

At this very moment, I’m feeling quite discouraged and desperate.

Just to clarify it’s an emotion (more cohesiveness! Seems unnecessary but it does add to your writing!!)

Let meI’m going to tell you what’s happening to me.

“I’m going to…” implies desperation as you are using a more forced tone of imperative!

The new book is easier to read than the previous one and that fact makes the reading be more enjoyable, more appealing, and more riveting.

“Be” is not necessary as “more enjoyable” -> an adjective (in this case). On a side note beautiful use of anaphora !

“The Kind Worth Killing” is a page-turnedr; the kind of book you start reading and can’t stop until you’ve finished it.

The reason it is “turner” instead of “turned” is because “turner” implies that it is a characteristic continuing into the future/present !

In a nut shell, although it took me longe to read it (more than a month, I read every dayand for over onean hour each day), it was worthwhile reading.

In English, this type of sentence would be too long by itself, instead, we would put the added, nuanced details in brackets to not disturb the flow of the simple sentence :)

A week earlier I finish a book,I only finished the book last week, and I’m already thinking about the next one I’m going to read.

Like someone suggested that I did, I pretended to write a review about “The Kind Worth Killing”, but, as usually happen to me, one thing leads to another and at the end, I’ve written about something completely different.

By the way, if you have any suggestions, please let me know it.

Suggestions is always referred to in plural in this context (referring to suggestions for books/movies/food etc.)

Not incorrect, just sounds a bit more natural.

Let me tell you what’ is happening to me.

Yesterday, I finished reading my lastanother book and, as always happens, starting a new one is never an easy task.

Theis new book is easier to read than the previous one and that factis makes the reading beit more enjoyable, more appealing, and more riveting, for me.

That was the case with the last book I read.

This seems a bit contradictory to the previous sentence, which seems to suggest that it is the new book that is more enjoyable etc.

I mean, my problem isn’t the lack of books I want to read, but which one to choose first.

That reminds me of that famous Forrest Gump’s quote: “Life is like a box of chocolates.

Like someone suggested that I did, I pretended to write a review about “The Kind Worth Killing”, but as usually happen to meas someone suggested, but as usually happens when I write a review, one thing leads to another and atby the end, I’ find that I have written about something completely different.

By the way, if you have any suggestions on the text / on topics I could write about, please let me know it.

I think you need to clarify here what sort of suggestions you are looking for.
