Questions about dense energies (Demonic/Entities)

I am a Reiki practitioner, and I love my job. I realise that I am a healing tool and I allow the healing angels to work through me. The results I have had sofar is in some cases miraculous, and in normal cases wonderful. I work in love and light, and see my customers as healthy rather than ill, as I believe this bring about better results.

Now my questions. I have a weekly klient who suffers a great deal. She has a bad past with lots of dark activities. While I work on her, sometimes it feels like I am being blocked and My right hand goes Icey cold and it feels like no energy is going out into her, but my left hand feels like it is overheating. I have to literally hold it about 30cm's above her so I don't burn her or myself. With the help of Avalokiteshvara, Kuan Yin, Jesus, Archangel Michael, Archangel Raphael, and numerous extra healing angels, I normally get things going again, but once my energy flows, it seems like she is in extreme discomfort. She gets choked and can't breathe. The visions she has while my energy flos freely is of being tortured to the extreme and I can see she is in physical pain. These sessions are extremely difficult, and slow, but there is deffinitaly progress. She is much lighter, and even at night, her sleep is better. Sometimes I can feel an entitie exit her and flee, and other times it visit me afterwords at night, but they stopped recently, because I have absolutely no fear of these things, and I am well protected. I have also had great success using a Tibetan singing bowl. Whenever I chant the Karuna sounds, I can feel the energies inside her go wild, and I don't know whether I should stop or go on. My only consollation is that I have the healing angels with me, and they guide me.

How do I proceed. I am not qualified to do exorcisms, and I don't know how to relieve her pain or help her besides working towards healing her spirit, cleaning her environment, or freeing her. She will not go for a formal exorcism, as the church did her great damage when she went to them for help. This is a beautiful soul in desparate need of help. I introduced her to some crystals, and how to place and cleanse them. I am also helping her with daily tips and helpful hints, but this my actual questions are about when I have her on the Reiki bed. How do I stop these blocks, and what am I doing wrong?

We have made a lot of progress, but the sessions are slow. In an hour's time, I only do what I do on other peole in 15 minutes. By then, she can't take any more. Another thing, after we finish and I thanked my angels, I feel drained to the point of collapsing. While I'm working I don't feel it though. I feel I am perhaps out of my league, but my faith is very strong, and I do not fear these things. I am willing to try new things, if anybody can please make suggestions. Any suggestion, it doesn't matter how small, will be appreceated!

I thank you for taking the time to read these words, and ask that everyone who read this far down, please pray for us both.

Love and light
Mystic Angel
