Welcome, "Brain".

You're in for quite a ride. I can promise you that.

I wouldn't worry too much about having a "bad trip". IMO, DMT doesn't dig into the contents of your awareness/psychology/emotions in the same way other psychedelics might. I've encountered components of DMT trips that were quite terrifying, but still taught me something great and were worth the experience.

Above all, you're likely to be simply awestruck. Bewildered. Dumbfounded, even. But one thing is for certain... This experience *will* impact you.

Do some reading and study about extraction teks. If you run into any issues along the way, you couldn't be among a better group of people.
