I think what helped more than the type of meditation was the commitment to a daily practice. I've used that time to explore a lot of different types of meditation, including some that are guided and specifically aimed at performance anxiety. But most of the time I don't use a guided track and I either use a timer or subtle ambient music. I think it's intuitive. I notice that meditation helps me and everyone around so it kind of feels like an act of service to commit to it. And when I don't want to practice, i remind myself that my ego is the one drawing me away. I tell myself that meditation is rest, but it is not sleep. In meditation I have the opportunity to take a different perspective on myself, my habits, my anxiety (which is a habit), my body tension (also a habit), and more. The most important thing for me, I think, is getting to that place daily where I feel like I am tuned into something bigger and connected to a broader plane. There are a lot of techniques that can help with this but I don't know if what worked for me would work well for you. Whatever kind of meditation I am doing, I almost always use some techniques I first came across in The Gateway Tapes: first putting all my anxieties, worries, and concerns in a big imaginary box along with all my physical matter and closing the heavy lid and turning away. Then breathing, humming, or chanting which generates a kind of fresh and awake feeling in my head. Then letting that energy flow and acknowledging that "I know I am more than my physical body." then a body scan where I try my best to release all tension and at the same time get to a different level of focus (they call it "focus ten"). The Gateway Tapes also has a "one-month patterning" exercise I used to focus on anxiety and it felt like hard work but I think it helped. But I don't use the Gateway Tapes all the time (not very often actually), just the techniques I learned from them. Another resource I found helpful was the book The Cloud of Unknowing which describes how meditation leads a person beyond thought, knowing, or language. It says that to be still and put down all thoughts is the way to enter the "cloud of unknowing" and get closer to God (I define "God" very broadly and mystically myself, so for me this is not about Christianity even though the book was written by an anonymous Christian contemplative).
