안뇽하세요.

I want to get a job for (as an) Plant Engineer. 

Especially, chances in overseas sites are more than in domestic Korea.
So, I need to have a fluent English skill.
Recently, I made a decision to participate ing (in an) English conversation club and buing (?) online conversation lectures for improving (my) English.
Yesterday I attended (the) conversation club (for the) first time.
I was not able to talk with the members who attended the club.
It's not easy to say (speak in) English and (I am) not used to exchange (exchanging) personal information.

Free talk is not easy just for me.

(Free talk is just not easy for me) 

I felt no idea in my brain. (this sentence doesn't make sense in English, you can say my brain went blank or I was out of ideas ^^)

In a Korean buzzword, I was in a condition of "멘붕".
"1. 멘(탈) + 2. 붕(괴)"
1. 멘탈 is a Korean pronunciation of mental
2. "붕괴" means corruption and it's oriented from Chinese word"
So, "멘붕" is a composed and abbreviated two words. The meaning of "멘붕" is corruption of one's mental such as psychological pressure.
Anyway, I'll not stop this meeting and try again.
I hope that I speak English fluently Someday.
Have a nice day!!

Thank you so much for teaching me a new Korean word ^^..

Your English is fine, good job! You just need a tad bit more exposure to native speakers to see how they phrase their sentences, if only my Korean was as good as your English lol! Good luck on your job hunting!!! YOU CAN DO IT!!! Fighting!
