Everyone, at one point in their life, has been a dumper or a dumpee. It's not pleasant to go through, but if things are not working with your partner, might as well pull the plug, then drag it on longer, investing time and varies of feelings.
No matter what end you are on, when dealing with a break up, I strongly believe that maintaining a clear mind, filled with positive thoughts will allow you to handle the emotions you are faced with, on a higher note.
Through my research (asked my friends and family), many confessed of preoccupy their time with activities, generally physical ones. This is a great idea because when you're active, endorphins are released. Just to let you know, endorphin is a chemical found in the brain. Once released, it will make you feel good, reduce anxiety as well as reduce your sensitivity to pain.
Here are some other ways to release happy hormones. :)
Another common thing to do, listen to love songs. Now I'm a sucker for a good love song, but when I was dealing with my break up and all the feelings that comes with it, I thought why not listen to empowering break up music. So with the help of my friends and family, I came up with a playlist that should keep your moral up. Now for my men readers...I mostly found women empowering break up music. But if you come across any songs that you think is quite suiting, please don't hesitate to share. Will definitely add to the playlist. ;)
I hope that when you are listening the playlist, that you get up and dance (if you feel like it) and start living again. Discover who you are all over, and find someone new. Good luck and hope this helped a little with the process.
