My ex was the only one for whom I was fearless, happy &amp; free. After 3 years, she dumped &amp; cheated on me for the past 4 months. That day when I confronted her cheating on me was that day when I started to feel afraid of the dark, I constantly feel like there is something that is just ready to eat my memories alive. Even when surrounded by everyone, I feel lonely. I just think about committing suicide all the time, but I step back from it every time because I worry that my parents won't be able to support themselves financially.
