Sounds like it stemmed from a bad break up.
I've noticed that young people tend to be over emotional in relationships. Not sure why that is. Maybe it's because us oldies have seen it, done it, and know this too will pass. In other words, it's not the end of the world.
I say this from experience of course. Of all the bastards I've been with the last thing I want my epilate to read is that I killed myself over one of them.
