Even reading a book for too long can feel "weird." And when you can't stop reading until the 6-8 hours is up, that could be a problem if you're in the woods on your own or something.
If you think you might need someone with you, you should probably have someone with you. These things can become self-fulfilling. Taking powerful drugs when in a state of (acute) apprehension or anxiety is not a good idea.
Obviously it might well be fine, by all accounts the stuff does tend to make you feel good, but doing any unusual activity for the first time on your own is very different to doing it with someone who's done it before.
This is MDMA we're talking about... not psychedelics. I've known people (SWIM and all that) who have taken it purely to abort a bad LSD trip. Pure MDMA is not going to produce anxiety. You can even be fairly functional on it, depending on the dose.
There are plenty of "I really wish this was over" drugs, and MDMA simply isn't one of them.
