losing sleep

I'm losing sleep.
I'm really tired.
I want to sleep but I can't.
I just can't.
I don't deserve to be tucked under the comforts of my duvet knowing that somewhere else people are out in the cold, hungry and bare.
I don't deserve to complain about my studies when just yesterday I saw tears in the eyes of an igcse girl - was it because of stress though, I wonder.
I don't deserve to even have the word "lazy" in my range of vocabulary knowing the island of prep I have awaiting me.
I don't deserve to think so negatively, yet it is what I do best, this afternoon as I looked into the eyes of the woman who sets her hope so high on me...

See?
I'm really tired.
I have to sleep now.
But I just can't...
