Don’t be scared, first of all. You have NOTHING to be worried about. I was in your shoes when I first tripped and the anxiety and fear was for nothing. If you’re feeling weird or uncomfortable remind yourself it’s just the LSD and it’s temporary. No ones ever died from LSD. It can’t kill you. I would suggest going somewhere you are comfortable. Maybe staying outside and looking at the clouds. Do a relaxing activity and listen to music and just vibe. If you’re feeling bad and want it to stop, exercising and drinking water is the fastest way in my opinion. If you’re feeling good then just go with it! Don’t think too hard about it. The trip won’t be anything like you’re expecting it to be so have an open mind and enjoy yourself.
