I'm sure a lot of people can relate to your experience lechuck12.
The toughest nuts sometimes crap themselves the hardest when they go there.
I applaud you for obviously doing your homework, doing an extraction, and getting ahold of a GVG. You'c be surprised at how few first timers go to all that length B4 actually trying the stuff out to see what the fuss is.
I'm sure, with your heightened respect, and better sense of what might be in store, you will do better next time out the box. Just remember that it will only last a short time, and you aren't doing yourself any physical damage by taking an endogenous chemical your body is designed to deal with.
Try to calm yourself with breathing exercise, and hold on to your intention to accept whatever you are shown.
It actually can be easier to go even farther than to go to the threshold for many people simply because at even higher levels of the experience, there is no way, time, or ability to freak out. The self-reflective ego that does the freaking is simply not functional.
Your problem could actually be the opposite one though. You may have taken too much. 30-50mg in a single breath would floor most experienced psychonauts and have them crying Uncle. From how you describe your experience, I would guess you only got a portion of what was loaded, and there is probably still a good amount on your screen / scrubber. Either that, or you got so ridiculously high that you have no memory of what actually happened.
Either way, you might want to dial in your trip a bit better towards your sweet spot.
All the best. Welcome to the Nexus, and be well.

"Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it." ~ Buddha
