How do you heal a broken heart?

You're in mourning. The death of a relationship is a lot like the death of a person.

So treat yourself well. Spend time with friends. Get good exercise and food into you (e. g. you'll feel worse if you don't physically take care of yourself, so please do so).

Give yourself permission to feel sad. But not forever and don't dwell. If you have a chance to do something different, then do so, whether it's go to a movie or reading or making something or doing a difficult task at work or school. Immerse yourself in these things and allow them to take your mind off things. They will, if you let them.

If you find that nothing gives you peace, or you are still in mourning after maybe six months have elapsed, or if you ever feel like ending it all, I urge you to contact your doctor as soon as possible.

It's going to be okay.
