Today I feel sad, tired, frustrated and all the negative emotions jumbled up together. I wish to vent it out, but all these feelings are just stuck here.

Then, I realized 有很多话我说不出口.

Sigh. Today's goodbye was the toughest. I feel so sad, so so sad... I didn't expect it to hit me this hard. Things will be different for sure. We can only hope for the best.
