What am I?

What am I?
I'm the water gathering in an abandoned tyre
What am I?
The grass to close to the fence to be cut
All feeling of expression of pain to deep to tell
I whisper I love you
I whisper I need to hold you
You warmed my heart by being close
Now the silence cries how cold my heart
Bitter indeed the tears I shed
My eyes bleed blood blue
My pains a tragic whirled and reaped
There is no pity left
I go to count the aspirin
Is it enough to kill the pain?
To cure a broken heart
No
You are the only drug
You are the cure
You are my true love
My are just my pills
You are the only cure
