What are some ways of stopping thinking about someone?

The thing is one cannot stop thinking about someone consciously. Repeating 'Don't think about him/her' to yourself actually means that you are thinking about that someone. Firstly, you need a distraction. It should not be an one time thing. The distraction might be making a new friend or getting a new hobby or even as simple as listening to music. The key is to keep yourself busy. Choose any activity and try it out with all your heart. If that doesn't work out, don't feel low. Go for another activity. But don't be too quick to jump over. Give it some time and your dedication. During all these process, be in love with yourself and believe that you are the best. Also, you gotta be patient. These things take time. Eventually, you will feel better and do have some hope. Cheers!

You could play some video games, go for a drive, cook a meal, hang out with friends. There are endless possibilities!

you have to distract your mind by finding something to concentrate on like drawing. It also helps if you distance yourself from that person.

Distract yourself by activities or other thoughts when that someone pops up on your mind. And keep doing that until you eventually forget about the person

Distract yourself by playing a game, going outside, taking pictures, or hanging out with your friends.

All you have to do is occupy yourself with something else that takes up all of your thinking capacities.

There are no absolute ways though there are certain things you can do to avoid thinking about someone like a distraction, having supportive people around , a hobby maybe.

There's never really any certain type of way to stop thinking about someone. Sometimes we can't control what/who we think about. The best way to try to stop is to let that feeling happen on it's own because I and/or other people could tell you ways that we feel is better for you to stop thinking about this one person, but that doesn't mean that it's going to work you just have to let it happen on it's own.

Do something that is just for you that you really enjoy. It could be a hobby, like reading, or an activity, like hiking or going out to a movie. Treat yourself, you deserve it.
