This hit me. Growing up I didn't have a lot of friends growing up. Two have stuck by my side despite my issues and they have become something of an important existence to me. We've been friends for close to 20 years now and I'm still grateful to them.
Know who your friends are and never let them go. If they can have your back at the worst of times, those are the people you need in your life. Be there for them as they have been for you.
