Break-ups are difficult, especially if you were actually in love with the other person. Whatever is happening to you is completely normal. I know this won't do anything immediately, but I've found the best thing to do in these cases is just hang in there. Survive. One of these days I'm sure you'll wake up and realize it doesn't hurt as much anymore. I'm sure this is a phase. Take all the time and support you need, but just survive somehow. :)
