How can I learn to be content and at peace?

A break up, even one that you initiated, may deserve some time and space to allow it to be complete.

There's a few ideas I'll throw out there and you can choose if they stick.  One is to re-invest in the friendships you have by setting up regular coffee get-togethers for example.  Two, get out in nature.  It's hard to ignore how grand and patient nature is, and it sometimes takes the pressure off what we should be and instead allows us to be.  And the last one I'll throw out there is to invest your time and energy in a project or achievement you've wanted to do for a while, but that perhaps you didn't have the time to.  Something related to a hobby such as sports or music, or related to your career.  Something that is 'for' you.  

Life knocks us off balance at times, and that's ok.  Self-questioning during these times can be a healthy endeavor.  Should you follow any of the advice on this website, continue to be kind to yourself about what you're feeling, and curious about why you're feeling that way.
