Fear of learning korean while In korea

So I joined a Korean university after thorough research and all for my Bachelors. My course is in English. However, learning Korean is obviously a must since I will be living there for 4 years during my undergraduate studies. My 1st semester was online. As well as my language classes (level 1). It was for 2 months (KLEC SOGANG) and honestly, it was very very easy and fun in the beginning. I was so into studying and all and it was going very well. However, after a few weeks, it got a bit harder. My speaking teacher was a very hard woman to please and tbh, no one really liked her because she just couldnt/wouldn't teach properly. She'd go extremely fast, skip honorific and a lot of important stuff and then expect us to Ace a test the next day. It was...difficult. horrible even. And since the classes were online...I hate to admit it...I started relying on cheating to pass.

Why? It got so frustrating trying to keep up with that teacher. I was the youngest in my class (17) and everyone else seemed older and much mature. No one really bothered to even chat after class or help out..I was very sad honestly because I asked for help I reached out.. yet...nothing

Anyway, so yeah, I lagged behind. My house in my home country was being shifted, so I had to miss a few classes time to time. But no one really helped catch up. I didn't have access to much to learn myself since I was overseas.

Well all in all, the final exams came, I got exam anxiety, cheated a little, fucked up. Interview came, I got an exam panic attack right there, no words could come outta my mouth. It was like I was dumb. I just couldn't speak, and the interviewer just kept asking stuff but it felt like I was lost...then she just ended the meet.

The exam anxiety part has been there since childhood...but never ever this bad that I froze.

Naturally, I failed my level 1 kap.

I had to study hard for my finals of university courses too..I will have to till the end so that's no excuse. Though I Aced these finals lol

However, my 2nd sem starts in March along with my RE level 1 language class. But this time, I'll be in korea, everything will be offline, in person.

(It's funny cuz I remember all of Hangul and many random vocabulary but I struggle most with grammar (so much) and writing and like those conjunction (stuff u add at the end?) And especially writing while listening...it's just super fast and I freak out)

So yeah, I believe majority of those problem is cuz of my fear of failure and exam ANZ I've had since a very young age. Like I've gone blank during exams in my previous school years too.

Anyway, my point being...I'm going to be in korea in like 3 weeks. And I'll start classes again. But I'm freaked out. So so much. Of not being able to answer in class, of not being able to write fast or cope up. So much more.

I fear I'll fail again. And I fear I won't fit in. I fear not being able to learn fast...I don't know...just...level one is so easy for a month, and then they suddenly drop a 10 ton truck on you...

And worst of all, I fear my speaking teacher. God I hated her, she just won't teach properly. It's like she hated teaching. She used to even burst out on some of us for no reason, or being slow. I fear her so much...

I don't know what I'm gonna do...it's too late to back out now.. I love my university course and I researched a lot in my flied and it's scope in korea. I have a whole plan.

But language? Gosh I'm freaking out.

Hangul is so easy..I know. But I struggle because I'm a bit slower than others...I just fear failing so so much that it stops me from studying or doing smtg in the first place.

And now that I'm typing out all of this...there's so many more fears coming out I didn't even realize I buried inside.

I hope someone here is willing to share some advice on how to pick up fast and maybe share their journey too?

I seek help...I'm so lost right now...

Anyway, thanks for reading my rant which I won't cross check cuz I hopeless
