Who cares for the carer?

Who cares for the carer?  
 
My door is always open  
My kettle is always on  
I’m here with a shoulder  
For you to cry upon  

You can tell me anything  
Your secrets I can keep  
You can phone me anytime, day or night  
Even when I am asleep  

If you live in solitude  
Or your heart is filled with grief  
If you suffer from low self-esteem  
I can build your self-belief  

I am everybody’s rock  
But who is there for me?  
Who cares for the carer?  
I think you will agree  

The more you do for others,  
The less they do for you  
It's the way society is now  
But that is just my view
