missing

Sometime i just can't control my emotion
Sometime i just can't help myself to stop overthink
Sometime i just can't stop giving people chance
Sometime i just can't  stop care about people who are not worth it
Sometime i trust people easily.
Sometime i just put others first than myself.
Sometime i put the blame at myself first.
Sometime i just feel insecure what they think of me , how im react , my personality, my appearance and anything.
I have come to a point where i am finding myself.
To stop think about little things
To stop to be emotional
But i just can't help. Maybe it just me.
I don't want my feeling or emotion to distract my mood and my surrounding .
Did i have any missing piece in my life?
I have family and friend  . Well that is the most important thing right?
Their love , care , honesty and sincere is enough for me
But why did i feel as if something is missing?
Sometime i just have no one to talked to
Sometime people whom i wish they will stay but eventually leave me .
Someday i need to learn to let it go
You know the feeling when one day you feel everybody againts you.
You know the feeling when you need to think twice just not to to annoyed others?
You know the feeling when you feel you're annoying to other so you just keep in silence?
You dont know how you end up to get that feeling it just came through ur mind suddenly?
So please can you
Now tell me what is my missing piece?
