Something about quiet words on the page describing what you are going through can be calming in a way little else is. It also helps to reboot the logic centers of your brain that your emotional state may have shut off or flooded.

Now is a fine time to do self-care rituals that, at other times, you might consider to be unnecessary splurges. 

Shop for clothes, accessories, or makeup. Get a new haircut. Nibble on some chocolate. Anything that boosts your sense of yourself as someone worthy of comfort and pride.

In the short term, it might reinforce or flare up painful memories, but it also normalizes the grief you are feeling so that you know you're not alone.

It’s probably best not to suppress or hold back one’s emotions, especially immediately after a breakup. 

However, the emotions can be so intense that they may not be appropriate for public display, so take time out, go somewhere private, and sob it out. Scream it out. It’s normal.

Family and friends can help, but make sure you recognize their limits as well. 

You may decide that professional help may provide a more neutral and long-lasting perspective. They can also point out deeper patterns of behavior or thinking.
