When I broke up with my first boyfriend, it didn't seem real at first. You need to cry, there is no good in keeping the emotion in. For the first few days, I cried. After that, I felt that what's done is done. There is no point dwelling on this, I need to find my own happiness. I did the things I like, ate my favourite food, concentrate on my studies, hang out with my close friends. It wasn't easy, but I needed something to distract me from thinking about the break up. I deleted photos I had of him, got rid of his things and any thing that reminded me of him. A clean break. With time, it will get easier and your heart will start to heal.
