If someone decides to walk out of your life, don't stress about. Everything happens for a reason.
A person can be one of two things, a blessing, or a lesson.
@Qcytz I'm familiar with how you feel
Unfortunately, the best medicine is time. It's hard, really hard. It hurts, physically. The best things you can do, is look at it like this; you have one less problem to worry about.
@Vegod_ Sometimes it's because the tectonic plates of life shift, work happens, bills, life gets busy. Things change, but it doesn't always mean that friendships do.
