Bro if I were you the absolute last place I would be is my mother's house. You should already be halfway across the country with a new haircut, new facial hair or lack thereof, and a new name. Chuck your phone and get a burner. Pull all of your cash out of the ATM. Call an Uber driver and then offer them cash to take you somewhere far away, off the record. They damn near killed you, I wonder if they told anyone else about it. If so, take advantage of that. Let everyone think you're dead and disappear. And why in the world would you ever drink anything that they bought?? Don't make a stupid mistake like that again, you might not be so lucky next time
