You don't have to run after people that don't want to be in your life, people that break plans, break your heart, and make you feel like you are not important.
You are worth so much, and it's time you start realizing it. You can get past your insecurities, they don't have to be your excuse or your crutch any longer. If you need something to change, change it, change is hard, but that's ok, it's better than complaining about it another day or two.
Be who you are, there are plenty of people in the world, and many that will love you for who you are. Quit changing to please people. Only change to please God.
Quit blaming, start being accountable and quit following fads, superstars, and other people that you only see from the surface. Follow Christ.
Live Live. It's Amazing.
