I take it that this is the same boy you were talking about here

Go to the year head again - don't even think about not reporting this boy yet again.
How can he have forced you to take pictures of yourself and send it to him, what did he say he would do if you didn't?
This boy's bullying you now, and it's not funny. Report it. Tomorrow.
Btw have you told your parents about this? You haven't mentioned them once in all this. They should know you're being harrassed, you're still a minor.
