I'm going through a heart break

take your time. cry frequently, and watch movies and tv shows that make you laugh. spend time with friends who can help distract you from time to time. and listen to loud music and sing along as loud as you can. whatever you do, don't try to bury your feelings. try to avoid rebounds and one night stands, if you can. they tend to make things worse. give yourself about six months or so, to recover, and then put yourself back out there, when you feel like you're ready to try again.
