Well, you could possibly scream and cry. I don't think a sitter is necessary other than to talk with afterwards. You'll be pretty much paralyzed if your dose is high enough. I once was projecting lots of sadness and negative emotions on the experience and it did not turn horrible. But a good set and setting can give the experience more meaning imho, at least on sub breakthroughs. Don't fear, because that's hindering you big time. Try to melt into the experience as quick as possible..
and leave all preconceived ideas at the door. It will be an awakening, own it and let it be your own.
