Come Mend My Heart

My heart has many splinters, it's bleeding once again. 
It has it's happy days, you know, it's jolly now and then.
My heart is like a broken glass, assembly can be hard. 
Just take your time and try your best, connecting every shard. 

Who is the one who qualifies to mend this beating muscle?
Who is the one to finally complete this ancient puzzle?
The job is tough, so careful now, commitment is required
My heart just wants to know what it is like to be desired.
