I took lsd 4 days before a drug test will it show up?

This was a drug test ordered by my probation officer at a place called TASC. Now these are high tech piss testing machines but the only drug anyone has suspected me of is marijuana and that she will be looking for other drugs in my urine. I told her I will be dirty for the marijuana and I have never done any other drugs not prescribed to me. If she sees that I did lsd that one time she said that she is going to send me to juvenile hall til I'm 18. that's not going to happen I found a special bullet with gl BBs inside to blow my brains out to ensure my death if this happens. My life is so messed up you have no idea I cant explain its to sad but I know there's someone else out there in the same situation. If I can p this test my life is set and I will be so happy please please give me an accurate answer.
