Figment of my imagination?

Four months down
And less grief now
So I have to ask
Were you ever around?

It seems like an age
Since you were alive
So now I wonder
were you just in my mind?

Perhaps I'm imagining
That you were really here
And you were never real
But there's no need to fear

Cause I have some proof
- A picture or two
And I can promise you this
I wont forget you
