Dear Old Brian,
Lots of people love you. You have loads of friends. And some of them care about you. They care about you a lot. They care when you're upset and unhappy, when you're excited and bubbling, when you're tired and grumpy, and when you're calm and melancholy. They notice when your mood changes and they're there to talk to when you need them.
So don't be all sad and mopey. No more of feeling self-pity, and no thinking, "I have no friends". Don't tell yourself that and insult your friends. Don't be all lonesome, hoping someone gentle or pretty will notice and come by your side. You can do better than that.
You know that God loves you. You have a bunch of friends. You're not helpless, so don't act that way.
I love you. Remember that too.
