Mature?

I have worked in this sucking cruel society for more than one year
so please don't expect me to be too silly，naive and stupid
I know what did you say what did you tell behind me
Please don't always show me your fucking stupid arrogant face
I don't care anymore I don't need your help
I don't want to lose my self-esteem
I know what I am doing
But
A very big thank to you.
I learnt to be tolerant. I learnt to be stronger.
Don't hate. Don't blame. Don't depress.
It's life.
It's how I am going to grow more mature and older.

I say :
If you trust me, you don't need my explanation ;
If you don't, it is just a wastage of time to explain.
I say :
Don't even look back. I want to go, I must.
Just let all the things go back to the origin.

And you,
a simple but complicate feeling
I don't know I should thank you or angry with you
Anyway, just
THANKS for treating me good, THANKS for treating me bad as well
at least I know I have grown and learnt.
