Academic English and Daily English, Please help?

Hello,
I am an international student who have been studying English for over 5 years. and been to Aus for almost a year. I'm now doing Bachelor of Laws at The University of New South Wales.
I'm doing okay so far with the academic terms in every subject, but i found myself knowing nothing about Daily English, most of the time I write, listen and read English in an academic way. I thought i could speak well but in fact i don't. Natives do not frequently use academic words in their conversions. They tend to use phrasal verbs instead, e.g. figure out, come along etc. It's weird to speak academically, that's why i lost my confidence in daily speaking. I wonder if someone might help me to fix this problem, please.
