It is better to formulate the sentence this way.

Last week was a strange time infor my country. Last week was a strange time for my country.

Firstable of all, there wereas the presidential elections and the results does not pleasent for min me. First of all, there was the presidential election and the results do not please me.

"First of all" is the phrase that "Firstable" sounds like. However "Firstable" is not actually a word in English.

Firstable of all, here were the presidential elections and the results doesid not pleasent for min me. First of all, here were the presidential elections and the results did not please me.

Firstable, here werely, the presidential elections took place and the results does not pleasent for min me. Firstly, the presidential elections took place and the results does not please me.

Firstable of all, there were the presidential elections here and the results doeswere not pleasent for mine. First of all, there were presidential elections here and the results were not pleasent for me.

I can see how you got "firstable" but it's actually first of all, English speakers sometimes pronounce things in odd ways. When using "were" for something slightly in the past , you could think of it as being a little more distant so we use "there" instead of "here".

I thought abouth the new changes wasould be an opportunity for my country, however the crowdpeople decided for the same side political side. I thought the new changes would be an opportunity for my country, however the people decided for the same political side.

"The crowd" sounds like a lot of people normally, but when you compare it to an entire country, it's actually really small (therefore it doesn't really make sense in this context).

I thought abouth the new changes wasthat would have been an opportunity for my country, however, the crowd decided for the same side political side. I thought about the new changes that would have been an opportunity for my country, however, the crowd decided for the same political side.

My way to express your message.

I thought abouth how the new changes was could bring opportunity for myies to the country however the crowd decided for the same side political side. I thought about how the new change could bring opportunities to the country however the crowd decided for the same political side.

I thought abouth the how the potential for new changes wasere an oportunity for my country, however, the crowd decided for the same side politicalpolitics of the masses sided against this. I thought about how the potential for new changes were an oportunity for my country, however, the politics of the masses sided against this.

I had a little trouble understanding exactly what you meant but I think this is what you were trying to say. The changes I made clarify that you had hoped the election could be an opportunity for change but turned out to be very negative.

AtIn the end, I think its necessary to apply more effort into my activitities yes, maybe to have more carefully when I go outside of my home. In the end, I think its necessary to apply more effort to my activities, maybe to have more care when I go outside of my home.

The common English phrase is "in the end."

At the end, I think it's necessary to apply more effort in my activitities yand maybe to havbe more carefully when I go outside of my home. At the end, I think it's necessary to apply more effort in my activities and maybe to be more careful when I go outside of my home.

AtIn the end, I think it's necessary to applyput more effort into my activitities yand maybe to havbe more carefully when I go outside of my home. In the end, I think it's necessary to put more effort into my activities and maybe be more careful when I go outside of my home.

"in the end" is the normal way to summarize in this context, if you changed it slightly you could also say "At the end of the day" "put" sounds more natural in this context, and in this context you would say "into" instead of "in" "Carefully" doesn't quite sound right in this construction, whereas you want to speak about your intentions to be careful. You could also say "and act more carefully when I go outside of my home." And it would make sense there.

I hope the circumstances of rampant crime in my country changes and the future will be better for everyone, but sometimes I think the people deserve what they chose.

Changed the order of a few things to sound more natural. The word "rampant" is often used when an over abundance of crime to describe that.
