An anecdote (please, help me with this text)

Last year I met with an English girl because I wanted to practice my English. One day she asked me about going to the cinema and I accepted. On our way to the cinema, we went by the door of a hairdresser salon. She told me that at the beginning of her stay in Spain she thought that a hairdressing salon in Spain was a place where films were screened because the word “peluquería” in Spanish has the same root that the word “película." I challenged her to go into a hairdressing salon and ask about the films that were being screened there, but she didn’t do it. It is a silly story, but it makes me laugh and I think that it likes me because that girl is as innocent and kind as this story.

"that it likes me"  I don't quite understand what you were trying to say here.

You could just say "... it makes me laugh and I think that she is as innocent and kind as this story." 

Thanks for sharing! I love hearing about the little confusions that occur when learning a new language. 

Hope this helps! 

ABOUT MY LIFE

WELL, I'M FROM VENEZUELA AND I WANT TO LEARN ENGLISH. I NEED to SPEAK WITH FLUENCY SO I NEED TO PRACTICE. I STUDY GEOLOGY, and MY FAMILY IS SO GOOD*. I HAVE TWO BROTHERs AND TWO SISTERs. At UNVERSITY I HAVE an EXCELLENT TEACHER BUT THEy told ME YOU NEED to SPEAK ENGLISH perfectly BECAUSE YOUR CAREER will be BETTER if you are WORKING IN ANOTHER COUNTRY. YOU NEED to PREPARE MORE, and take more COURSES ABOUT PETROLEUM. I LOVE to TRAVEL AND MY BIG DREAM IS to SPEAK ENGLISH PERFECTLY.

I THINK I NEED MORE VOCABULARY, PRACTICE on SKYPE OR I DON'T KNOW.
MY EMAIL IS GAHR1996@GMAIL,COM
IF YOU WANT to TELL ME.
THANK YOU.

Very well written and that is awesome that you are working so earnestly on your English. Please remember that if you have a conjugated verb in the sentence, the verb that follows must be an infinitive. For example: 

If you want TO tell me (want is conjugated and, therefore, must be followed by 'to tell' instead of tell)

Also, you stumbled on a tricky grammar point; 'to tell' vs 'to say'

They told me

They said to me

Here is an article that can help you more with this common mistake:

*My family is so good. This sentence sounds a bit awkward to me. I would say something like:

My family is so good to me

My family is great

I love my family

My family is very important to me

etc

Finally, as was mentioned by Leigh Mumford, Caps makes the reader think you are yelling. Try to only use it for emphasis or, if you are in fact yelling! 

Hope this helps! 

I'm looking for somebody

My name is Lucas, I am nineteen years old and I am looking for somebody to teach me how to speak/ write English. 
I am from Brazil (write brasil here ), I speak portuguese and my skype is luucaas.123

I recommend practicing your use of the verb 'to be' 

Hope this helps! 

Drunk

I was drunk last night, so I'm not comfortable today.

You could also say, "...so I'm uncomfortable today." 

Also, and you may know this, but that feeling is called being hungover. 

I was drunk last night, so I am hungover today.

Hope this helps!

I would say, "How is the weather?" and "Here, it is cold and sunny."
