Hard to go to sleep

Everyday at night I miss you
Everyday at night I remember the first time I saw you and the last time I saw you
I remember that I went to a whole different world when I saw your eyes for the first time
When I remembered that at night it's hard to go to sleep
Thinking that was just the past, that I will never see you again
The tears I've cried could do an ocean or a river, but you don't seem to care
And that hurts me the most
