There are plenty of ways to soothe your anxiety after a breakup. Just know that it will take some work, and it won't be immediate. 

Here are some strategies:

• Try meditation. Quieting your mind and practicing being present can help quell anxiety not just during meditation but throughout your day as well.
• Avoid alcohol. Alcohol can make you feel more anxious, so it's best to cut it out for a while after a breakup. 
• Spend time with your support system. If you're prone to rumination (which can affect people with OCD especially), spending time with family and friends can help get your mind off your ex.
• Take care of your basic needs. Eating nutritiously and getting enough sleep helps lessen anxiety. In fact, there are certain foods that fight anxiety, like leafy greens, legumes, liver, and beef. 
• Start or maintain an exercise routine. Exercise is a powerful tool to bring down anxiety, as it boosts endorphins.  

Talk to a Professional About Your Anxiety

There's no shame in talking with a professional if your anxiety is taking over your life after a breakup. If you can't concentrate or you find yourself caught in an anxious thought loop that won't stop, it's probably wise to find some help.

Cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), and eye movement desensitization and reprocessing (EMDR) can help reduce anxiety following a breakup. With CBT, a therapist will help you recognize and reframe negative thoughts that could be contributing to your anxiety. DBT helps people develop emotional regulation skills. And EMDR helps people process and heal from trauma.
