I don't know what to do with my self

this is a song which i wrote about someone very close to me.

I sit and face the silence,
In a corner of my room.
Finally I'm free
And I don't know what to do,
With myself...

Remembering every conversation,
That we ever had.
Replaying every memory,
Untill I feel I'm going mad.
And I don't know what to do,
With myself...

Now you're out of my life,
But you may as well be here.
Because I only think of you,
And wish you could be near.
And I don't know what to do,
With myself...

Everything seems different,
It feels like it's all changed.
And now after months of thinking,
I wish I never sent you away.
And I don't know what to do,
With myself...
