Physical pain: bruises, cuts, gashes, broken bones, concusions, cracked ribs...
Emotional pain: depression, anxiety, disorders, migranes....

Physical pain heals with medicine...
Emotional pain heals with medicine...
But with emotional pain there ones part you cannot heal...
And thats the emptiness you feel inside
Its always gonna be there
No matter how many millograms you take
No matter how many grams you smoke
No matter what you do
Its always gonna be there
But you do learn to live with it
And it gets easier
And soon understanding fills the void
You dont know why its there
You dont know how to fix it
But you understand that its there
And you understand nothing is gonna fill it
So understanding itself  fills it
