Which Part?

There is a difference when someone wants you to be a part of their life and when they want only a part of you in their life. 

Sunken and Stranded

Myriad things i want to do
Spontaneous i want to be
But not at the cost of what 
I am trying hard to not be

They say I'm living my life great
But I fear a future with regrets.
There is still no grip of 
What i really want to perfect

I feel like I'm trying
But i can't quantify any.
I know my Achilles heel 
That's killing my zeal

I am embarrassed to admit 
I've not progressed one bit
A fulfilling life i seem to dilineate
But deep inside I'm insecure and diffident.

I want to change this now 
But I'm still feared by the 'but how's'
I want this haunted feeling to end 
For too long now I've been feeling 
Sunken and stranded.
