My cousin has been suffering from depression from the age of 14 or 15. She had been under therapy and had visited several counselors over time. Recently I found out that she has been taking a prescribed pill called Nitrosun for the past 3 years. When I Googled this medicine I was shocked to see the reviews of users speaking about the highly addictive and even destructive nature of this pill. It leads to memory loss, cognitive damage, not to mention side effcts that may result in putting the nervous system at risk. When I told my sister about this, she told me she read about them long time back, that she knew about the side effects. But she can't do without them anymore. She has become so dependent on them she feels her life will collapse on her if she doesn't have the sachet of pills with her all the time. She won't tell her parents or doctor for fear they will stop giving her the meds. I can see he withering away before my eyes. She is an adult, but I feel I must intervene and tell her parents. What do you suggest?
