Collaege

Big news,! I joinstarted collaege.

It ihas been almost a semester since I join collagestarted.

The collaege is so far from my home country, and I am struggling because of homesickness.

Here in theat collaege, everything is nice so far including the environment, the food , and the dorm.

However, the education isclasses are freaking hard.

I studiedy day and night, but there is no change.

I changed "studied" to "study" since you are currently studying at college and it is not just something that happened in the past.

Now I am confused.

I do not know what should be my next move should be.

Collaege

"Collage" means to make art through sticking various materials (fabric, photos, etc) to a surface.

Big news, I joined collaege.

"Joined" is correct, but sounds weird, because "join" is usually used for jobs or clubs. The phrasal verb "get into" would be more natural ("I got into college.")

It ihas been almost a semester since I joined collaege.

You use the present perfect continuous (i.e., "It has been,") because you are talking about a timeframe that continues into the present (the semester continues to today.) You use past tense (join + ed) because you are talking about the time in the past where you joined college (you are not continuing to join college to this day, because you already joined.)

The collaege is so far from my home country, and I am struggling because of homesickness.

A more natural construction would be, "I am struggling with homesickness."

Here in the collaege, everything is nice so far, including the environment, the food , and the dorm.

"Here in the college" requires a comma after it because it is a dependent clause (i.e., it is not a complete thought.) A comma is also needed after "so far" because it connects an independent clause to a dependent clause.
Also, in lists of two or more, "and" is required after the final comma (e.g., "I have an apple, an orange, and a mango.")

Your sentence goes:
Dependent clause ("Here in the college", because there is no subject (who is in the college?))
-> Independent clause ("Everything is nice so far," because you have a subject ("Everything,") and a verb ("is."))
-> Dependent clause ("Including the environment, the food, and the dorm," because you have no subject (What includes these three items?))
Independent clauses need a subject and a verb.

However, the education is freaking hard.

At this point, I do not even know what to do.

"Don't" (contraction of do + not) would sound more native here ("At this point, I don't even know what to do.")

I studied day and night, but there is no change.

"I have studied," or, more natively, "I've studied" would be correct, because your studying continues to today.

Now, I am confused.

The most native construction would be "Now I'm confused," but for "correct" English, a comma is needed after "Now."

I do not know what should be my next move.

The most native construction would be, "I don't know what my next move should be."
