I took 17 and 1/2 oxycodone today. Will I be okay?

I OD'd on purpose. I wanted to kill myself. That was like 9 hours ago though. I got really tired and dizzy. Then I went for a walk. I stayed out walking for about 6 hours, feeling really out of it and dazed, just wandering around aimlessly. I came and took 4 ibuprofen for some reason. I don't even know why. I put on a movie, but I could hardly keep my eyes open and I felt really nauseous, but I didn't throw up, and like I couldn't feel my body unless I remembered I was in it. It felt like I was detached from it. Then I got up and went upstairs in my house to my laptop, feeling slightly more conscious. Then it's now, and I still feel really sleepy and dazed and nauseous. If nothing serious happened by now, will ANYTHING happen?
