What is crystal meth withdrawal like?

I am writing a script for my final project in school sort of the media production equivalent of a thesis and one of the characters is a meth addict who suddenly doesn’t have access to his supplier. He has been addicted for a year or two and otherwise, he is a healthy, fifteen-year-old boy.

So, collective, can you tell me about meth withdrawal? If you can’t, can you suggest some resources for me to research? Thank you for your help!
