You grew on me like a tumour 
And you spread through me like malignant melanoma 
And now you're in my heart 
I should've cut you out back at the start 
Now I'm afraid there's no cure for me 
No dose of emotional chemotherapy 
Can halt my pathetic decline 
I should've had you removed back when you were benign 
I picked you up like a virus 
Like meningococcal meningitis 
Now I can't feel my legs 
When you're around 
I can't get out of bed 
I've left it too late to risk an operation 
I know there's no hope for a clean amputation 
The successful removal of you 
Would probably kill me too 
You grew on me like carcinoma 
Crept up on me like untreated glaucoma 
Now I find it hard to see 
This untreated dose of you has blinded me 
I should've consulted my local physician 
I'm stuck now forever with this tunnel vision 
My periphery is screwed 
Wherever I look now, all 
I see is you 
When we first met you seemed fickle and shallow 
But my armour was no match for your poison arrow 
You are wedged inside my chest 
If I tried to take you out now 
I might bleed to death 
I'm feeling short of breath 
You grew on me like a tumour 
And you spread through me like malignant melanoma 
I guess I never knew 
How fast a little mole can grow on you
