Hannah was through with all of the lies, rumors, and betrayal. She was on the edge and her reasons gave her a huge push to end her life. She committed suicide by overdosing on pills. Hannah Baker had a rough start to high school and from then on everything just became worse. No one was aware of how much their actions effected Hannah's life. Hannah Baker impacted the lives of many people with her tapes. It even says that at the end of the book Clay recognizes a possible victim of suicide, Skye Miller. She was showing the same signs as Hannah and Clay couldn't let her go.
This book teaches us how easy it is for someone to become weak and lose hope. We should think before we speak because we don't know what others are going through. Let people know that you are there for them and even something as little as smiling can change the minds of the people around you.
