I wish everyone the best in the future! This happened to me actually.I worked for a terrible MSP, and when I gave my two weeks they walked me that day without pay. Try to give it to your boss in person. If that isn't possible, send an email and confirm through a call that they received it. At any rate, you don't want to leave on bad terms. Bosses change and you may want to come back in the future. While you won't have to pretend everything is great in your formal notice, you also don't want to go into detail about negative experiences. After your termination is processed, you will no longer have access to your DOE accounts. You've found a new job, but now you have to let your current employer know.
