Honey.....If you need to take the meds, by all means take them. The Reiki may help you and I truly hope it does. I am a Reiki Master and I think that it is fantastic to take this anxiety of yours and conquer it! You are taking the right steps by doing the self-reiki on yourself. What level are you? Panic and anxiety are real issues for you. Just acknowledgment in itself seems to be a great start for you.
