Oh my gods, you almost made my brain bleed! What in the hell is "the cusp of magick"?
Okay, so there is some seriousness in your whole post that I think I can respond to. To help control your gifts, you definitely want to wear black tourmaline, hematite, and blue lace agate. Stay far away from clear quartz, citrine, and carnelian. Every morning when you wake up, I would recommend doing a grounding and centering. Repeat this grounding and centering as often as you need to keep the crazy at bay. Once you're feeling calmer, it may not be a bad idea to make an appointment with a general practitioner to rule out a chemical imbalance in your brain.
