Need Advice

Hi so before I start I will admit what I did was stupid and I will never do it again. Anyways here’s what happened;

On Friday at 12 pm, I took 20mg of Vyvanse for my ADHD. Later that day, I drank an entire bottle of Smirnoff and Tito’s with my friend and blacked out within 30 minutes. When I woke up on Saturday, there was vomit all over the place (in my hair and on the couch). My friend managed to get back to her house but when I woke up I experienced continuous vomiting throughout the day. Every time I tried to stand up, I would vomit again so I laid in bed the entire day. The vomiting finally stopped around 7 pm on Saturday, but I could only manage to eat half a burger. Today (Sunday), I am feeling foggy, tired, disoriented, and off. I’ve been hungover before but never to this extreme. I have school tomorrow and I feel cognitively slow and I don’t know what to do. Please help
