What is wrong with me?

Let's start w/the drugs im on (prescribed) I take Lamotrigine which is generic for Lamictal. This drug is used to treat epilepsy and bipolar disorders. i have twitched at made ticks and had ocd since i was really little. i take 2 200mg pills a day. Today i accidentally took a double dose. Then my gma gave me 2 advil for my back(it was called somethin else, starts with an "a") and then took 2 ibuprofren cuz i completely forget bout the lamictal. i went into work at 4 today and 30 minutes after i got there my left eye felt like it was out of place it felt like it was looking to the right. im a cashier at a grocery store and i couldnt read the numbers or count the cash, i became really dizzy and ran to the bathroom everynow and then. I'd throw up and p out over and over till i got off which was at 9:30. My manager found me in the bathroom. my lips were blue, my gums were white and i was cold and pale. I went back to work, thinking i could. i kept ping out and swaying, my speech was slurred. i have not been takeing any other abusive drugs beside prescriptions. My nose was bleeding and i was dripping sweat. I'm scared this is goin to happen again. it felt like all a dream cuz i couldnt hear myself tlk or other ppl talk. it was like Charlie Brown, but im being serious. Does ANYone know wats wrong w/me? i seriously need help.
