Some good music, writing about how you feel so you can get over your broken heart... A little shopping won't hurt neither. Keep being yourself and looking good, that person is gonna wish later on they never hurt you.
First of all, self respect. Don't let anyone be more important than u, except God. Second, find a good song that reminds u of all the reasons NOT to be with that person! I call it a "kiss off" song, but wtv u call it, u need reminded of the bad stuff that made u angry. The things that person did that showed they didn't love and respect u. U r worthy of respect! Just remember that! Then, read a good book and let ur mind be somewhere else for a while with a good cup of hot cocoa!
giving yourself time&letting the right one in not just anyone you'll know when you meet that special someone! plus it takes time. If you rush in it's not gonna feel nor be right. sometimes you just have to let love come to you!
Don't sit at home and dwell on the past. Although it hurts, get up and get out! Hang out with friends and family. Whatever you do, don't think about it. Do something to keep your mind active. Join a gym. It's a great way to release the bad energy and look hot as hell when you're done!
Give it some time, eat ice cream, talk to your best friend, and punch a pillow or scream in one. Give your heart to have time to reheal it self and you too so get up take shower and say "your name" I can get though this when the time get rough!
