Admitted to plagiarizing (second misconduct), and afraid of expulsion. In need of advice
Consider asking to meet with your Professor (e.g. during reception hours). At that meeting, or by email if you can't schedule a meeting, ask her for a copy of the report she submitted. Alternatively, ask the disciplinary body if a procedure has been opened involving you, and if it has, ask for a copy of the complaint through there. If your Professor asks what you need it for (which she shouldn't, it's obvious) - tell her that you're anxious and it's important for you to know how your story was reflected to the higher authorities, given that it involves all sorts of circumstances and details.

This may not solve any of your problems but at least you'll know what you're up against better.
