I need help.

[z†cĸα]

Don't go to sleep at 6 in the morning, it's not healthy, it leads to even bigger depression. I know you're shy, but try and talk to some people, in school if you see a lonely kid, a girl or a guy, just talk to him, he probably has same interests as you, just try, then go out with them, it's fun, trust me. ;)
Also if you're scared to sleep, try to find the reason for it. Maybe nightmares? And stop pretending to be happy, you can also find help for your depression.
