You are likely not at a significant risk of deportation though anyone who has stayed beyond his/her authorized stay may be placed in removal proceedings. You should quickly make the necessary corrections. You may want to consider working with an attorney to avoid future rejection. I am also concerned given you requested an extension of stay. You may be found to have misrepresented yourself in requesting an extension of you had no intent to depart. Speak to an attorney before resubmitting.
