Stuck In The Past

How will I know what my future holds
If I'm always thinking about the past
Dwelling on things that happened
Wishing that I could go back and change them
Knowing that I can not
Which only makes things worse
And then I'm completely stuck in the past
Unable to get to the present or future
And searching for a way out
Then I find that way
And it is suicide
Because that is the only open door
Everything else is locked
The only open choice is suicide
So I open the door
And never look back
Again
