Things to believe in:
Stand up for yourself whenever possible.
Be a royal bitch when it's necessary to be one.
Allow yourself to laugh out loud, especially at yourself.
Fight for yourself even if you are fighting alone.
Hold your own hand when you are sad until you find your happy place again.
If they don't love you, make time for you, value your existence, they will never change. Free yourself for the weight it takes to carry the burden of them around.
Life is a series of bloody battles, so hang on with claws out, kicking & screaming until the enemy goes down.
