Heartbreaks are difficult, but they're necessary as well. Personally, I've fallen in love many times before and at times it seems that each breakup seems more painful or even more difficult.
It has been difficult for me to simply leave behind people I saw in the near future walk with me and for that reason, I managed to make a list of tips that could perhaps help other people who are going through that difficult time, so without further or due:
Accept the loss: The end was inevitable and can hurt you further.
Vent: Talk to someone about it and write down everything you're feeling.
Just cry: Don't deny the pain you're feeling, cry until you're tired of it.
Do not torture yourself: Don't get stuck on memories, don't call him/her, do not reach them or search them online.
Give yourself time to heal: Enjoy your time alone and find yourself again.
Stay busy: Do the stuff you always wanted to do and start a new project!
Everyone overcomes a broken heart in different ways, but these tips could help you.
