The Wellbutrin could help, but may not.
Either way, you need to dig deeper and find out what is causing the emotional outbursts. It sounds like he was struggling and lost what he felt he was good at and what was important to him (hockey), so he’s given up altogether. Sit down with him and ask him how you can help him. Ask what he enjoys and what he wants to spend his time on. Write it up as you’re talking. Then make a contract that parents will support him and provide opportunities with those things he wants, and he will do his best at school and in his interactions with parents.
Right now he really needs some wins.
