I'm 21 now and I took accutane when I was about 16. I can tell you that your daughter's Acne
was simply a symptom of a much bigger problem internally. My health was very poor at that age and I experienced unhealthy emotions as a result. Hormonal health is a very important factor in determining mood and emotion, and Acne
is one sign that these hormones are unbalanced. Accutane, like many other drugs, simply masks the symptoms while further worsening the state of health, hence the common side effects of "suicical thoughts," etc. Believe me, I've been through the erratic behavior and emotions that you've described and no life experiences or situations could bring about these feelings in a healthy human-being. It just isn't normal.
I'm guessing that your daughter took a second round of Accutane because her Acne
returned? Mine also returned after the first round, but I looked for an alternative route. My dermatologist told me time and time again that diet had nothing to do with acne, but I inherently knew this to be wrong. I began to keep a log of my diet and my acne and I realized there was a very strong connection. An extremely strict diet coupled with exercise decreased my acne by maybe 70%. I'm leaving out a lot of other things I've tried, but it was not until I discovered these forums that I completely cured myself through the liver flush. I'm not only acne-free, but every aspect of my health has improved including my temperament which has gone from pessimistic and depressed to happy and optimistic.
The human body is very resilient and it is definitely not too late for healing. It took me several years and much work to completely reverse my health, but it has been the most rewarding experience. Your story of your daughter really hit a spot, and I wish you guys the best of luck. Hope this helps.
