“I’ve been hurt, lied to and broken hearted.I have felt alone when I couldn’t afford to be. But at the end of the day, I had to learn to be my own best friend, because there’s going to be days when there will be no one there for me but myself.”
Forgiveness doesn't always lead to a healed relationship. Some people are just not capable of love and it might be wise to let them go, along with your anger. Just wish them well and take care of yourself.
Live life fully while you're here. Experience everything. Take care of yourself and your friends. Have fun, be crazy, be weird. Go out and screw up! You're going to anyway, so you might as well enjoy the process. Take the opportunity to learn from your mistakes: find the cause of your problem and eliminate it. Don't try to be perfect; just be an excellent example of being human.
