I really need help I fucked up and don’t know what to do

I (17f) was having a celebratory weekend with friends where I drank a bit the first day feeling only a slight buzz, then on the second day I had an small piece of edible and 4 hits of a dap pen. I woke up the next morning feeling fine and having no hangover so I decided to drink, I had in total like 9 shots and 3 beers. I had never gotten this drunk in my life nor have I consumed this much of anything kind of substances in such a short period. The morning I woke up from the partying, I have been feeling horrible symptoms of hangover and maybe other worst things. I have a weird numbness throughout my body and my brain feels slow and Im on day 3 of the hangover and nothing has gotten better. I am scared to tell my parents because they don’t know about my occasional drinking ( again I have never gone this hard, this is the first time I have done any kind of substance in months) but I think I may need medical help if it doesn’t get better. Please tell me if anyone has dealt with the symptoms and if they went away eventually. I also have been struggling to sleep and I am writing this at 5 am.
