What drug did my friend give me?

So one of my friends are kind of on the wild side, I dont hang out with her much anymore.Anyway yesterday I had a terrible headache and she said she had Tylenol.I took it not thinking anything of it.The whole day my family was asking me what I was on and I thought I was acting completely normal. A woman cussed me out for taking her parkin and I didnt care I jumped out of my car and starting yelling at her.I forgot half the stuff I did.I stole gum at the store. I openly talked about my private life as if it were nothing.I am convinced that this pill was some type of drug because never ever in my life have I ever acted so uninhibited. I am a very well mannered person and keep my business private. She swears it was tylenol.I know it wasn't.And the best part... I have to take a drug test next week for work! What should I do and what is this pill. It was white and long thats all I remember.
