Hi M....my heart goes out to you. It is so difficult when our children or loved ones are ill. A good friend of mine had epilepsy though high school.
It does sound like the meds could be part of the issue as well as they areas of the brain that are stimulating the anger response.
I raised five daughters utilizing a lot of natural remedies and primiarly alternative medicine. Not sure what your background or experience may be but we know how that everything is comprised of energy. The body is electromagnetic in nature. Our thoughts, feelings and emotions have a cumulative affect on the body, and vice versa. Stress is one of the hardest things affecting all of those areas.
Utilizing energetic therapies you can accomplish in a few sessions what can take months or more to accomplish with talking therapy alone.
When the body's energy system is balanced, many functions return to normal rather quickly. The body is designed to heal itself given the proper and necessary elements.
It is totally private and non-invasive. You could try a treatment for your daughter and evaluate the effect you observe in her demeanor and over-all well being.
If you would like to read more about the options and the process, please visit www.focusedenergyhealing.com There's a video on there from a local news broadcast about energetic healing and therapies. YOu can also read people's personal experiences. This particular person is someone I have known for many years and he has helped our family tremendously.
It works on the energy system in a way that is similar to accupunture but it does not use needles.
If you have any questions or would like further insight please let me know.
Many blessings to you and yours M.!
