How do I stop thinking about someone I'm obsessing over?

To stop thinking about someone your obsessing over you could do things like listen to music ( silly kind like old Brittney spears and Destiny's child) get your self happy also going out with friends won't hurt :P

Stop thinking to stop think. And think about someone you love. Simple as that. Try to make it practical

It will be hard, but look for a distraction, like any activity that will keep your mind away from that person.

This is extremely hard. The only thing that helps me is doing other physical activities like hanging out with friends or running so that my mind is busy. Slowly over time it will get better.

From my experience I joined the gym and I worked on myself I made new friends and decided to go back to school and learn something new in order to forget the person I felt I was obsessing over.

Firstly I'd suggest getting some physical distance if you can. Then work through why you are obsessing with them? Figure out what you want from them and if it's healthy and/or possible. Failing that, distraction is key. Spend time with friends. Join a new club. Read or watch t.v. Anything that will take you out of your head for a little while.

I try to see why my life is beneficial without them. Do I really need this person in my life if I have been fine without them for so long? What are some cons of the person themselves? What do you not like over the things you do? Sometimes when listing pros and cons of the person you may realize they might have more cons than pros. Obsessing over a person is a common occurrence I think. Finding distractions like story writing or creating art can be a great way to get your mind off the person. And maybe you'll find out things you never knew you could do.

Maybe draw, or do something you love to do. That'll probably take your mind off it, or you can speak with friends. :)

Channel your thinking into something else. Be it hobbies, other friends or work. If thinking about someone too much is dragging you down, find a way to make use of productively.

Obsessive thoughts often appear to waste so much time. Students find it so hard to study when they keep day-dreaming about their crush. One minute, a guy is sending countless phone calls, the next minute his relationship ends. Grieving the loss of a past relationship can be difficult and the person may succumb to depression. Sometimes, talking about your obsessive thoughts to a listener on 7 cups can provide relief. If it still is a problem for you to distract your brain from spending all your time fantasizing over somebody, you might have to seek professional help. It might make your life much easier.
