Je suis trés fatiguée

Frankly, I haven't been sincerely happy ever since I knew you and I should let go. I've been putting on a fake smile and insincere laughter. I think I'm good at acting. I've been acting like I'm happy and I pretend to be strong. I blink away my tears every time I feel like I'm going to cry.
I hold my chin up, even though I just wanted to fall down and cry on my knees.
I don't mean to whine or what so ever, but sometimes I couldn't hide it.
I feel like I'm being possessed by this despairing sorrow.

I am very tired.
