Maybe they can't, but if you feel like it then you need to look at the bright side and follow that path, things will always get better, I promise :D
And if your hurting find a friend that you can talk to instead of being depressed, then it will at least give you some hope and confidence
Can I be your friend? A definition of a true friend is not whether you know them or not, it's if they know what you're going through and that they can help.
*hugs* hope you feel better!
