Faden quartz
This is quartz that has come under stress itself and been fractured, then repaired itself again. They all contain a line where the quartz fixed itself and are strange, squashed, twisted shapes. This crystal can be programmed to heal anything and increase your capacity to heal yourself (the body is amazing you know). Carry one of these and programme it to help with panic attacks and heal your life. Keep it with you in your pocket at all times.
