Hello
It is unfortunate for your daughter to have to suffer so much at such a tender age.
I would like to encourage you to read up on the information I have posted on my website (link above) and especially, I encourage you to investigate the many excellent uses for pure pharmaceutical grade L-Tryptophan (an essential amino acid) in very successfully treating not only PMS/PMDD but many other depression disorders.
It is a very safe natural alternative to chemical drug treatment, and can really be of excellent help in your daughter's situation. Further to that I encourage proper nutrition and regular exercise.
Please feel free to ask questions, etc.
All the best,
Anthea
