There isn't a cure for a broken heart, but the next few steps might just help you cope with the pain of heart break, and come out the other side a winner.
Give it Time. You must accept that heart break isn't solved over night. It will and does take time. If that's three months, or a year, everyone is different. The sooner you accept this however, the easier it gets. I can guarantee you that.
Cry. Keeping your pain and feelings bottled up makes it worse. Even if you are crying alone, it helps. Let the boo hoos out, and you'll be surprised at how much better you feel. Don't be scared to cry, it shows that you're human, and that you cared for that person, but know that you have to move on.
Keep busy. If you were in a relationship and kind of ignored your friends for a little while, see if they'll forgive you, and arrange a get together. Become the best you can be at work, and start whipping up a storm in the kitchen. Misery loves boredom, so don't give yourself a chance.
Cook. I find cooking, baking - the act of throwing ingredients together, which then turn into a meal, incredibly satisfying, if it doesn't turn out tasty, who cares, you're trying something new, and focusing on the mixing, and correct quantities, you won't have time to be sad.
Get moving. Exercise is a fantastic way of relieving stress, and taking your mind off the heartbreak. Working out alone, or in a full gym can really ease the pain you're in. Plus the more you exercise the better you'll look and feel.
Travel. If possible, try and remove yourself from the location of the person you've broken away from. Get out and explore your city, or book a trip somewhere abroad for the weekend. You need a distraction, and a new city is one of the best ways to take your mind off someone because you'll be immersed in a new culture.
Sleep. Sleeping can be hard when the person you used to cuddle is no longer there. Instead of crying into your pillow try lavender drops on your bedsheet to help you nod off. Sleepless nights are a result of a break up, but you must try and get some shut eye, otherwise you'll feel even more fatigued. Get some rest, and you'll feel a whole lot better. And the saying goes...everything is better in the morning.
Ending a relationship is always difficult, not least because love is lost, but because all of your usual habits have to stop. So instead of texting them each morning, or talking every evening, try evening classes at the gym, or try a new venture because a broken heart won't stay broken for too long, when you're having fun.
