What is going on?

How come so many people are dying from drug overdoses?Is it alright to take prescription drugs when stressed? or tired? I don't think so.I wish I could understand why people are dying from drug overdoses but I don't.I also wonder why people would take a lot of prescription drugs.I am aware that prescription drugs are good but too much is bad.From what I know people don't purposely overdose but as I have already said I want to understand what goes tyhrough their mind when they see prescription drugs.A person who is addicted to prescription drugs or tries to stop but can't needs serious help because this could result in accidental overdose which most of the time results in death.I hope this crazy thing ends because it's scary and it occurs too much.People who are in their twenties are dying..because of this.People like women who have little children are dying because of this. I know that women ... some women get postpardum depression after giving birth but could that drive some women to take more prescription drugs than necessary?I have no clue.I have no idea.All I know is that it is sad to hear that people are dying from overdoses.Hopefully this will stop occuring because it has to and it is very heartbreaking when you lose a loved one over something like an overdose.
