It has been a long time since I wrote something here.
Time really passes so fast.
My emotions always change a lot, and I've been busy about 'dealing' with it. Guess people never are satisfied with their life, even though we have a better life compared to those who have an even worse experience.

For me, love is an essential spiritual supplement in my life. I always look for somewhere that my heart can "land", so I can focus on my life. However, I really doubted and lost confidence of my belief in love. Maybe I'm not suitable for having a relationship. There are always questions in my head, but, to be honest, I always know the answer in my heart. I just don't want to give up so easily... but it's so tiring to persuade myself and adjust unstable emotions... 

Sigh...

Good job!  Mostly minor errors with tense, but it all made sense.
