I think you need to go back to school and relearn life's little lessons.
Let me help....these are just a few....
To have a friend, you have to be a friend.
I won't try to rationalize the other ones but will offer you this advice. Yea I know, never give advice right? Wrong.
Look for the good things in life as well as in people and don't dwell on the unpleasant.
No ones perfect so don't expect them to be.
Forgive, forgive, and forgive.
Do all things and make all decisions to glorify God.
Love yourself and love others even more.
Be thankful for what you have and don't be bitter about what you don't have.
Work hard and do a little bit more than required.
Take advantage of the opportunities given to you.
Unto thy own self, be true.
Treat other people as you want others to treat you, no matter how they treat you.
I could go on but I know you really don't want the advice right?
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
