A few years back, I had a really good friend who suddenly disappeared from the social scene. At first, I thought I did something to offend her. Then, when I found out she suddenly dropped out of university and gave up her dreams, I got really worried. I became frantic and tried to contact her. After a few months, I finally managed to reach her and found out her problem was a toxic relationship. Her boyfriend had become too controlling and obsessive with her. It looks months for her to get out of the situation and years for her to heal.
