When you say anxious, do you mean you suddenly feel fear and are afraid of going on (exiting)?

Maybe it would help when you imagine (although actually I believe it is this way while we are alive) that you do never entirely leave your body but only send out a probe/drone to explore?

I have made good experience and with joyful anticipation, that is when I best project. In other words, put on a smile and be looking forward to the experience is the best strategy.
