How to Stop Loving Someone Who Doesn't Love You

Recognize that pain is normal. When you love someone who doesn't love you back, it hurts. It turns out that “heartbreak” is a very real physical sensation: the pain from rejection activates your parasympathetic nervous system, which is responsible for things like your heart rate and muscle tension.[2] It’s natural to feel hurt if you love someone who doesn’t return the feeling. Accepting that your feelings are normal can help you process them.
Romantic rejection can actually trigger the same response in your brain as withdrawing from drug addiction.
Psychologists estimate that about 98% of us have experienced some form of unrequited love. Knowing you’re not alone may not make the pain go away, but it may be easier to bear knowing that you’re not the only person to go through this.
Rejection can also cause depression. If you notice any of the following, get help from a mental health professional immediately.
Changes in your eating or sleeping habits
Feelings of hopelessness or helplessness
Changes to your normal mood
Trouble controlling negative thoughts
Thoughts of harming yourself
