There are a lot of things in life that I don't have control over. Who comes in and out of my life. A lot of the details and events that happen.
What I do have control over is my response to the situations that I have no control over. I can break down and cry. I can scream and yell. I can take out my frustrations on others.
Or I can be disappointed but still hold my head high. Keep my dignity and my pride. Try to not let it affect me in the long run.
I try to do the latter. It's not always easy, but I try.
