Aio I think I was drugged last night

I went out to a party with some friends I was the designated driver so I didn't drink alcohol but I drank a glass of coke I remember feeling sleepy and from there it went black several times I woke up and saw people above me in the morning I woke up in a bed without my underwear my whole body hurt and I was full of bruises my phone was full with messages from my friends who were mad at me because they thought I left without them what am I supposed to do now I wonder if I should go to the doctor but I’m scared I’m overacting and it’s nothing
