You are in big trouble dude. I know lot of Nepali’s in a same boat like you and they havent been successful to adjust their statuslater to permanent resident . Keep in mind even a week of not being in status will be a problem later . You will find out once you start getting  RFE’s. While adjusting. As mentioned above by help you help me, things like illness or mental health problem might ease this situation however you have to provide proofs and evidences from a physician and this job is not easy. I am not trying to scare you but i know lot of nepali students being out of status and later making up stories to regain their status .
