Self Doubt

I feel numb to what's around me
And I always feel alone
I don't feel like I belong here
It just doesn't feel like home
And yet I just stay here
Letting day and day pass by
And every night I lay in bed
While letting the tears silently cry
I feel like I'm a burden
Like I should just move on
I feel like I'm just staying somewhere
When i should have been long gone
My self doubt is over whelming
And I can't fight it away
And I feel like if let everyone down
If I just left and so I stay
But I think I'm trying to hold on
Because I dont think I'm ready to let go
Everyone says it'll just be fine
But can they really know
