How does Self Therapy stop panic attacks and anxiety?

The diagram below shows how anxiety can spiral into something like a panic attack. Similar phenomena can cause social anxiety, public speaking fears, and other anxiety issues to intensify as well. Self Therapy basically reverses that intensifying spiral. It's a simple approach that can be applied to just about any anxiety sensations you're experiencing.

If negative expectations lead to anxiety, wouldn't "positive thinking" reverse it?

As you may have discovered, severe anxiety is very difficult to "relax", "meditate", or "positive think" away. In fact, using such approaches may even increase anxiety sensations. That's because, when we're suffering, we tend to practice such techniques with an underlying fear-based desire to avoid our fear-based emotions (like anxiety). When that happens, our best attempts at "positive thinking" are often rendered negative and counterproductive (like adding fuel to the fire).

Will this method work if I'm currently taking [trademark name]?

Self Therapy empowers you to deal with anxiety sensations directly, rather than continuing to avoid or suppress them in any way. If you're currently using any drug (legal or illegal) that "numbs" your emotions, it will likely be difficult to benefit from this approach. However, please speak to your doctor before making any changes to your medication.
