Can anyone tell me what I should do?

I am totally depressed last few week.
After sometime, I'm much better now.
No matter how I want to hide or run, the truth will still be out someday.
But for the time being, I would like to be silent.
To pretend I didn't know anything.

Today I discovered that other people know about it.
Should I find out from them first?
Or should I stay in the silent?
I having exam in 26 Nov and 7 Dec, I think after my exam, I will take my initiative to find out.

I maybe will be more depress by then... my dear friend, please if you cannot find me after 7 Dec, don't worry. I might be just wanna be alone first.

Thank you!
