If somehow no one appears on your behalf, tell the court your attorney was/is hospitalized with a very severe medical problem. Tell the court to call her office, or the hospital for details.
Don't reveal her precise medical problem in open court.
Stop emailing her office, call or visit her office to ask your questions.
The worse that will happen is the matter will be DELAYED.
If she can't practice for months, her secretary or paralegal will suggest options.
Whatever you do, don't try to be a lawyer. Request the matter to be postponed.
