Are you not feeling well, or are you unsure whether you are doing well? Or is one of your friends not doing well? Go to the emergency room. They will help you.
You can always knock on the door of the emergency room. For a band-aid because you have a blister or paracetamol. And they also help you if you don’t feel well after using alcohol or other drugs.
What happens in the first aid, stays in the first aid. Everything you discuss or happen there is confidential. So you can tell the first aid crew what you’ve been drinking or taking. Then they can help you better.
If you are unable to go to the emergency room yourself, ask the security or crew to call them. Do you see someone else not feeling well? Do not leave him or her alone and wait for help to arrive.
