It's got to get better. It really does. It can't get much worse. You are not as worthless as you keep thinking you are, even if half the bosses have nothing good to say and your hours are down by ten. You won't always be body-and-soul tired. You wouldn't always be this discouraged. This will pass, things will get better, and you're not a loser. You still have your friends, it's summer and most people are away. It's not that no one wants to talk to you. It's just a rough patch. Things will get better. They have to.
