23 février 2022 - Vivre avec Cle covid ou Zzéro Ccovid ?

Technically, "covid" isn't capitalized, but capitalizing it isn't a big mistake at all

Quand la situation devient incontroôlable, et en faqu'en réalité, la mortalité deliée au covid n'est pas si hautgrande quand on ase fait vacciner, faut-il re-penser notre moyen de le combattre ?

"en fin de compte" ("all things considered") would be even better than "en fait" or "en réalité" here
You may write "nos moyens", if you consider we have several strategies to fight it

Le gouvernement ici a interdit lesaux citoyens de proposer l'idée de vivre avec Cle covid.

Interdire quelque chose À quelqu'un: the thing you forbid is the direct object, the person that is forbidden is the indirect object

Laes restrictions de "« distanceiation social" ese » sont renforcées et les masques sont désormais obligatoires même quand on fait des l'exercisesce dehors.

If you mean "to work out", it's "de l'exercice" (always singular and indefinite); "des exercices" would insist on several, definite kinds of exercises
Also, I suppose your government took more than one measure about social restrictions, so it'd look better to pluralize the word

Je suis étonnantée !

"-ant" endings are like English "-ing" endings => present participles. An active action. "Je suis étonnante" = I'm astonishING (to other people)
"-é(e)" endings are like English "-ed" endings => past participles. Passive states or actions undergone by the subject. "Je suis étonnée" = I'm astonishED (I'm in the state of being surprised)

La loi est là pour protaéger la santé des citoyens mais cettes nouvelles règlement as/mesures ont fait l'opposéinverse.

You've talked about several measures, so => plural
"un règlement" is a set of measures/rules people have to respect, like the paper listing what you're authorized to do (or not) when you're at school

Tandis que moi, la citoyenne, n'a pasi même pas une seconde pour l'm'y opposer.

moi = je => ai
"n'ai même pas une seconde" would mean you lack time; if you mean you lack the opportunity to do so, "n'ai pas une occasion/une chance de m'y opposer" would be better
s'opposer À => pour m'Y opposer

Le confinement peut sauver quelques vies, mais ça réeprésente aussi unde grandes pertes d'économieques.

Just like in English where "losses" is often a plural, it's usual to pluralize the word "pertes" in French when there are a lot of things being lost

Quand j'ai vu dans les nouvelles que les gens de Canada, deCanadiens, les Franceçais...... peouvaient faire la protestationer contre leurs gouvernements, et que l’Australiae avait déjà réouvert sones frontière, cs.... Cette liberté me manque tellement.

The "Australie" proposition depends on "j'ai lu que", so a "que" is needed to mark the relationship between them
The English language uses the word "people" a lot but overall it's better to use (capitalized) nationality adjectives as nouns, in French
réouvert = opened again (as indicated by the prefix "ré-")

You may end a relative clause like "quand j'ai vu" with three periods "..." as to indicate the rest of the sentence follows logically
A famous example is when (for instance) a kid is being mischievous and runs away from you, you may tell them: "oh toi, si je t'attrape...!"
It's implied "if I catch you => you're gonna have a bad time !"
If everything was in a single sentence, you'd be forced to have "quand j'ai vu [...] cette liberté m'a tellement manqué" (both actions related to each other)
