these days i really very confused about the future.

my colleague J will quit from our company, her last working day is on next Friday,

she is adorable and has a sense of humor, we always make some kiddings when in leisure time,

hope she will hunter a good job;

acutually i also intend to find a better job;

however, i'm afraid of facing a new environment and afraid of challenging,

just like yesterday, two of our customers visited our fty and the boss asked J and me to join their lunch,

during the one and a half hours of lunch time, i mostly acted as a listener,

what should be a good chance to show my ability in front of boss and customers, but....

it seemed i failed to dig out a topic and i'm not familiar with everything of Japanese,

i really hate what i was like now, i desire to improve oral English,

i'm not confident to take a new challenge and pressure,

what can i do to help myself? is there any methods to master fluent English?
