fall to pieces

Feelings deep inside my heart are just too complex,
they are pieces a little here and there,
and I don't know how to make them all in connection to tell a story.
My thoughts are there,
I am ready to tell,
but I just can't make a simple sentence to tell you the story.
Somehow it's like something missing here or there,
but when I am trying to find those missing's pieces,
I realise that they are actually here all the time!

This is something very abstract to explain or tell in words.
One thing I can assure is that,
you love,
that's why you care,
and it just will makes you mad that you don't know who you are anymore.

I am kinda like lost,
am I deeply in love?
