Hey what's up y'all,. I've been learning English for some time now and I wanna live in United States, t. That's why I'm writing this post.

"Hey what's up y'all" is very informal and casual. Nothing wrong with it if that is your intended tone. In fact it's so informal, spelling it "yall" is also acceptable in the context you'd likely be in when using it.

I wanna see if my eEnglish is good enough to work with other's and well...

"I wanna see if my English good to work" is again acceptable in very informal situations. It's especially found in certain urban venacular. I would try to avoid in a formal situation.

I just need to communicate with other's ( hope I spelled that right ).

Plural "s" and not the possessive "s"

Here's some info about me tho,ugh. I'm 18 yo aears old. Actually I just turned 18, so Happy Birthday to me!

"tho" and "yo" are abbreviations and shorthands used in very informal writing. Don't use them if a professional tone is your goal. Otherwise it's fine on places like social media and texting with friends.

My passion is going to the gym,. I love that stuff, like watching Ronnie Coleman back in the 00s and 90s when he was in he'is prime just.... Just seems nice to see how someone can be that strong, a. Anyway I'm looking forward to it, and I wanna live with peolple, like a lot. I love being social etc.

"going to the gym", "fitness", "working out" a lot of options to mean the same thing.

I'm not the type of guy who want's to spend his life alone.

I want some adventure too, v. Visiting some bars with homies, and meeting some girl is are things on my list tooas well.

If someanyone is reading thatis, thanks for your time and h. Hope you're haveing a good time over there!

Hey, what's up, y’all,? I've been learning English for some time now, and I wannat to live in United States, that'which is why I'm writing this post.

Added commas in your greeting to show you correct grammar, but in casual situations like texting, it was perfectly fine. I also replaced “wanna” (which again is fine informally) with “want to” to show the correct expansion.

“Y’all” has the apostrophe because it is a contraction of “you all,” in case you aren’t aware.

I wannat to see if my eEnglish is good enough to work with other's and well..s.

I just need to communicate with other's ( hope I spell that right )s.

In English, having an apostrophe followed by an “s” after a word (for example, “mother’s”) shows ownership (also called “possessive”). For example, “That is my mother’s bag.”

The word you wrote twice, “other’s,” is the possessive form of “other.” The plural “others” is what you meant.

Here's some information about me tho,. I'm 18 yoears old, and I actually just turned so H18; happy Bbirthday to me!

“Info” was fine, but I wanted to show the full word for your benefit.

I changed your paragraph slightly to teach a few things.

To join two independent clauses (full sentences with a subject and a verb), you can use a coordinating conjunction (examples: and, but, or, so, yet, for, nor). In your text, “I’m 18 years old” is a full sentence, and “I actually just turned 18” is also a full sentence, therefore I added “and” to join them together. This makes your sentence more grammatical complex and will help you write better. In English, we don’t join more than two independent clauses together using a coordinating conjunction.

“Happy birthday to me” is also a full sentence. Since we don’t want to use another coordinating conjunction, you can use a punctuation mark called a semicolon (the “;” you see) to join two sentences. We use it when the second sentence (after the semicolon) is related to the first sentence (before the semicolon). An example is: “I played baseball yesterday; it was fun.” You could leave it as, “I played baseball yesterday. It was fun,” and that is perfectly fine. Using a semicolon, however, makes it flow a bit nicer. Consider the semicolon another tool in your writing toolbox. You may see it again in my corrections to give you more examples of when you can use this often-forgotten piece of punctuation.

My passion is the gym,. I love that stuff,everything related to the gym, like watching Ronnie Coleman back in the 2000s and the ‘90s when he was in he'is prime just... seems nice; it is cool to see howthat someone can be that strong, a. Anyway, I'm looking forward andto [insert you are excited about]. I wannat to live with other peolple, like a lotsince I love being social etc.

Notice the semicolon I used?

You said you are “looking forward.” In English, we say that we are looking forward to something. That “something” is something we are excited for.

I'm not the type of guy who want's to spend his life alone.

I want some adventure too, like visiting some bars with my homies, m. Meeting somea girl is a thing on my list too.

If someone is reading thatis, thanks for your time, and I hope you have a good time twhere you are!

I wanna see if my eEnglish is good enough for me to work with other's and well...

other's = someone else's
others = different/other people

I just need to communicate with other's ( hope I spelled that right ).

Here's some info about me tho, I'm 18 y/o actually just turned 18 so Happy Birthday to me!

Happy birthday!

My passion is going to the gym, I love that stuff, watching Ronnie Coleman back in the 00s and 90s when he was in he's prime is just (indescribable)... It seems nice to see how someone can be that strong, a. Anyways, I'm looking forward to the future and I wanna livspend time with peolple, like a lot, I love being social etc.

No need for "etc" here because it's not a list of items. And when you change topics completely (gym -> looking forward to the future) it's better to start a new sentence.

I'm not the type of guy who want's to spend his life alone.

"want's" doesn't exist :)

I want some adventure too, visiting some bars with homies, meeting some girl is as, etc., are things on my list too.

An example of where to use "etc."
"a girl" or "some girls" is okay, but not "some girl" (correct grammar, awkward meaning)

If someone is reading thatis, thanks for your time and hope you have a good time there!
