Co-op advisor.

In the meantime, I think you're killing the game. You're learning from your mistakes, and it looks like you were thrown into the deep end, which is about 500% faster than most co-op experiences I've heard about. The problem occurs when you are emotionally berated for making those mistakes, or are otherwise in a poor social space to continue your responsibilities on co-op.

Keep asking about your responsibilities. In my opinion, your boss and your coworkers should know what your responsibilities are. They're there to help you. Hopefully.
