Best thing to do would be to apply for another AP or to wait for AOS. You will not receive another student visa if you're not enrolled. You also cannot get a student visa if you're currently waiting for adjudication of your immigrant petition.
I'm surprised, however, at your case. You cannot be legally in the US on an F-1 (I-20) if you are not enrolled in an American school. Your visa and I-20 becomes invalid one months after leaving school and you are required to depart at that point. Even though this is not connected to your question and certainly none of my business, I would consider getting a touch with an family immigration lawyer if there is a chance that you accidentally overstayed your visa. Good luck.
It depends on when you withdrew from school. If it has been more than 180 days between the time that you autorrized period of stay expired (30 days after the day that you dropped out of school) and the received date on your I-485, Do NOT leave the US until you get your permanent resident status for any reason. You have very likely either been out of status for more than a year and are subject to a 10-year ban on reentry or for 180 days and are subject to a 3-year ban on reentry. AP cannot protect you from this... Sorry, but you're probably going to have to hang tight until you become a permanent resident..
If you want a more definitive answer, you have to provide more information.
