I agree with you in some points.

I agree how you feel devastated.

Same thought also come to my mind.

Usually most of website where provide 'Language Exchange' are commercial.
They connect professional teacher/member and students.
This site, too.

Also, English is one of the most preffered word, many people want to improve their skills.
But correcting 'perfect' is very difficult even who using English as a mother-tongue.
I found myself I cannot correcting Korean in grammer ways, even I am Korean, and I have a very good score in Korean in my school days.

Such as you, you don't need any corrections in grammer, in my view.
Also you cannot be friends with your english teacher.
It is hard to correting, and they want to get job.
Nornal english user could not correcting your writing easily.

But you still want to improve your skills, right?
What you need is, how to express your opinion more persuaded ways.
For that, you are better to take a class 'how to write" or running a personal blog.

Are you majoring Sociology?
I am majoring Sociology.... so I want to talk dare.
I thought you may think more critically when you want to call your writing as a "sociological topic"

Language Exchange is a one of commercial decoy for selling sevice "class".
Learning language is also reflect power of the country.
English is most powerful language in the word.
If you good at English, you have more chance to success.
People who native in English have no motivate to learn other language.
(It is bitter truth...)

But, English native and not native has a common.
Even a English native, have to learn HOW TO WRITE.
You has a great English skills.
What you need is improve your writing skills and critical thinking (or thinking more sociological)

Thank you.
Have a nice day!

It is better if you watch out 'space' in your writing.

But I could get it what you want to say.

Great!

p.s. Is your friend is your teacher?

add) wow your some grammer is better than me. I always confuse using "거예요, 거에요".

        But I still give you some recommendation for expressing your thought better.

----------------------------------------------------------------------------------------------------------------

이사할 거예요

저는 이사할 거예요.
아직 우리 집을 안 팔고 새로운 집을 안 사는데 지금 새로운 집을 찾아요.   
그리고, 우리 집을 팔기 위해서 매일 청소를 많이 해야 해요.

-> vague expression.

     Are you want to sell your house? but not selling yet? and not buying yet new one?

--> my recommendation.

아직 우리 집은 안 팔렸고, 새로운 집을 산 것도 아니지만, 지금은 새로운 집을 찾고 있어요.

그래서, 우리 집을 팔기위해서는 매일 청소를 많이 해야해요.

--> more smooth expression.

아직 우리 집이 안 팔려서 새로운 집을 살 수 없었어요.

그렇지만 새로운 집을 찾아보고 있어요.

(새로운 집을 구하기 위해선 지금 집이 팔려야하므로)

그래서 (우리집을 팔기 위해서는) 매일 청소를 열심히 해야해요.

이사는 어려워지만 어렵지만 재미있어요.
지금과 같은 도시로 이사하지만 아빠의 학교에서 더 가까이로 이사 하고 싶어요. (아빠는 교수예요.)
흥분이 돼요!

->  It is literally translated English expression, "I am extied!"

      More smoothe one in Korean is, "신나요", "기대돼요"
