It is not selfish to love yourself. 
But it is selfish to let yourself drown in sadness. 

You keep on hanging in a toxic relationship.
You keep a friendship that only you who is supportive.
You  just let other people put you down.
You keep on running after someone who doesn't value you.
You keep on working to a job that you don't enjoy working.
You keep on procrastinating.
You let your family think that you are a loser.
You keep on putting negative thoughts in your mind.
You hate God.
You think you are not a worthy person.
You keep on blaming yourself.
And to anything that makes you not love yourself stop it!

When you learn to stop all the bullshit in your life you will learn to 
LOVE YOURSELF!

Have the audacity to LOVE YOURSELF. Leave anything that worries you.
Talk to God. He is always there to listen to you. Whenever life puts you down just talk to him and pray. Trust in Him through good and bad times. I tell you if you keep your faith in Him, God will guide you thru all your journeys. God's presence will teach you to love yourself.

Love yourself and you will learn to love others.
