How to deal with intense heartbreak and betrayal?

I am so sorry this has happened. It sounds like a very hurtful situation.  I imagine you may be experiencing many questions and wanting answers such as "how could they move on so quickly when I have been experiencing heartbreak? Did we not feel the same way about each other?"

Wanting answers during break-ups is a normal experience. We want to make sense of what happened to us and the feelings we are experiencing.  However, we may never know truly what happened as other people might not have the insight into their behaviors that we would need to really know what happened. This sounds like it was a quick turnaround for your ex. We don't know what that means. 

When we are going through heartbreak: know that your feelings and experience are real. We will often experience such visceral emotions that it feels as if we are in actual physical pain. There has been research to show that the same areas of our brain light up during a break-up as when we are experiencing an electric shock.  

This is because we are social beings. We experience attachment and belonging as very real needs. When we lose those connections, it is very difficult.

It's important to take care of yourself during a break-up. You can allow yourself to feel your emotions and allow them to pass through. It may be helpful to journal your thoughts and emotions so you can let them out. It's also important to lean on your social support during this time.  Spend time with people who love you. 

When we experience a break-up, we can often feel like we have lost who we are. It might be helpful to return to activities that make us feel good and give us a sense of purpose and pride. Maybe even try new activities.  This could help return your confidence and also offer a healthy amount of distraction during this time.

Overall, make sure you are giving yourself grace to experience your emotions and heal. If you need to take naps or you feel like going for walks to clear your head, follow those instincts and know that your experience is valid. 

I'm cheering for you and your healing right now.
