I met up with my friends :D

You say met up with because it is past tense and it sounds better than saying just "met"

yesterday , I met my friends to drink all night long :)

-> Yesterday , I met my friends and went drinking all night long :)

Always start a sentence with a capital letter, you say "went" because it is past tense since it was "yesterday"

we talked about lover problems and the job matters

-> We talked about problems about love and matters about our jobs. 

It was quite desperated but happy because just we met

-> I was quite desperate but happy that I met my friends.

I dont quite understand what your trying to say in this sentence but heres another way to say it

I'm not sure when we can meet one more time, but I'm waiting until that time

-> I'm not sure when we can meet again, but I'll be waiting. 

Your sentence is good but some language can be changed to make it sound better C:
