P.S. THere is a new fingernail polish developed that all you have to do is dip your finger in your drink and it will change color if there are drugs in the drink. I don't know if this is out on the market yet but I know I got roofied and if they had had this I would have been wearing it to be sure. Maybe look into availability for future outings. Also you are one of our own, we will always support you.

I agree with IAMGROOT, you were the victim, since when is it not OK for a female to celebrate and expect not to be assauted? The shame is on the ones who did this to you and the ones who would deny you care. At the very least Id say a rape kit is in order BUT they have a backlog of those sitting on shelves unprocessed years down the road. We live in a corrupt society. You have my sincerest sympathies but you have nothing to be ashamed of. Hold your head high!

Um, this is just my opinion, but...

1. YOU ARE A VICTIM! You need help, not punishment. You did not voluntarily experiment with drugs, someone slipped you a "mickey," as they say. A loving and caring father would have maybe growled at you for a lack of vigilance, but then would have had you seen immediately. You blacked out? So without going into the TMI zone, people do this for a reason so you should be thoroughly examined.
2. You are legally an adult and if you're on the family medical insurance, you don't need dad's permission. In fact, privacy laws protect you FROM dad (and mom). So either set an appointment or just go to the emergency room so you can be seen. Your health and safety are paramount here, not what your dad thinks you did wrong.

I hope this is helpful.

Nobody can stop you from seeking medical help.

Congrats on graduating. What are your plans afterwards? I would have gone to the hospital-your father can not control you. At 18 you have right to medical care.

Welcome to the club. I’m 52 and have blacked out many times. It happened just a few weeks ago with others in the same state of drunkenness. Don’t let it bother you, shake it off and move on. Wait, what? Do you know that someone roofied your drink? Were you raped? How did you get home? A visit to the hospital may be the best thing for your foot and maybe a drug test along with a rape kit.

Ok, you're well young enough to be my daughter. I might be upset depending on who you were hanging out with but you're still a baby in my eyes and going to be subjected to the world.
I would've taken you to the ER to make sure you're ok. Concussions are no joke.

It takes no time at all to "dose" a drink. It happened to me once, thankfully didn't hit my head but it messed my night up.
Please be careful and take this as a lesson of caution. I'm sorry you're having salt added to your wounds by those who should be watching out for your well being.

The fuck is wrong with your dad? Go anyway. Get a friend to drive you there. Concussions aren't something to blow off.

I'm not sure what you mean by "shunned." Are you kicked out of the family or grounded?

I see that you are 18, so here are my suggestions.

First, you take your adult self to the doctor if you need medical attention.

Next, if your dad is always that mean, you start saving your money and move out.

Third, try to be more careful when you are drinking. Keep your eye on your drink at all times. Know when enough is enough so you don't black out and get hurt.

You ARE allowed, by law, to seek medical assistance. If you do go to the ER, ask for an exam to determine if you were sexually assaulted. If you were drugged, you are the victim of a crime. You DID NOT "do this to yourself".
Your father cannot prevent you from getting medical attention.
If you're old enough, get away from these people.

OK, now I'm going to shame your dad. Not allowing you to go to the hospital for a possible concussin because you did this yourself is criminal. That said, high schoolers out drinking is always a mistake, but I should talk, I was one myself who did that. The other, much bigger criminal act was by the one who slipped something into your drink. I hope you are OK.

Figure about a month's or less worth of contriteness.

Go to the hospital.
