Also please pray my son learns somehow to be a person
with better character.  If he fails to become such I will have failed as a 
parent
and that will be the worst thing which can happen.

Angel, I don't think a child having a poor character necessarily means 
you've failed as a parent.  Remember, your son has free will, and can and 
will choose how to live his life, whether his choices are wise or foolish. 
Our job as parents is to do our best to teach them well, but not to live 
their lives and make their choices for them.  That's their responsibility. 
I'm sure you've done the best you could in teaching him right values.  If it 
were true that the children's characters always indicated what kind of 
parent they had, what would our characters and sinfulness say about God?  So 
please don't beat on yourself.  I will pray though that your son comes to 
see the error of his ways and changes direction.

Hugs,

Peggy
