'Hair raising' is an expression that usually makes reference to the hairs on the back of your neck. This expression would be used when describing moments of great anticipation or urgency such as the emergency described in this passage.

A breakout is a driving manoeuvre. This passage is in reference to the President Johnson assassination in Parkland.

These past days I noticed that my attitude is getting worse. For example, I was at my cousins birthday and I didn't have the confidence to mingle with my friends. So I sat in the corner alone when suddenly one of my friends came and played a joke on me. I was not really in the mood for her jokes so I shouted her. My cousin and my friends looked at me and I felt like I was such a bad person but that wasn't really my intention. How can I overcome this attitude? I feel so different now, this is not me.

 

suggestion: consider the tense in which you are writing. Since you are telling a story you should be focusing on the 'past tense'. Also look to shorten your sentences rather than relying on commas.

Hi, My name is Maria

My name is Maria. I live in Russia and I have just started to learn English. I know lots of individual words  and I understand the rules for the preparation of proposals but I have very bad grammar.

Based on the context you put the words in it would suggest that the moment the president fails to act that there will be people within the organisation that will begin to make some of the presidents decisions for him/her to ensure that law and order remain. If not, as mentioned, the alternative will be anarchy. Note: I'm not sure where you are getting your material from but those with English as their native tongue would struggle to follow what the author is saying here

This statement is often used with sport. For example you were at the point where you had nearly lost the game but you have started to play well and you are closing the gap between your score and your opponent. That would be 'fighting your way back'

I show my sympathy for Ma Jiajue

I want to tell you a story. Nine years ago, a Chinese university student named Ma Jiajue killed four roommates. That year, every student told their roommates that they "would appreciate it if they didn't kill them" and thanked them for not doing so upon graduation. This is a true story.

 

i'm not sure if that was a joke or a story as I couldn't determine the punch line. Plus you finished with the statement that this is a true story.
