How do I stop thinking about a friendship that has ended?

Avoid that friend and his memories and try to find new one dear :) Do not mess your life for the one who has no value for you, you're precious so you have to care for your feelings.

Well...Speaking from my personal experience, the lost friendship isn't what hurts, its the replacement thing that sucks. We see them give our position to someone else that what hurts the most. The "friends" turn into "ex-friends"and thats what breaks our heart, We feel betrayed and replaced like we never mattered to them. So....when I felt the same way, I tried few things and trust me these really help. If u r an introvert, try reading books, completing all the pending assignments, doing something that makes u happy, try to be creative, if u r an extrovert- make new friends, compliment others (this makes them happy to talk to u), take part in group discussions more and smile everytime u feel happy(not everytime though people willl think u have gone crazy becoz of ur recent loss), try to take part in outdoor activities more, make urself busy probably too busy to notice the change. Show them that not everything we lose is a loss. And that remember this-if ur absense doesn't make them feel bad or incomplete then may be ur presence never mattered to them in the first place.

There is no easy or simple way to stop thinking about ended friendships. In truth it is difficult and can cause as much if not more heartbreak than ending a romantic relationship. I have spent many months and years pondering on friendships that ended, but have recently adopted a new mentality which has forever altered the way I feel about ended friendships. "people are only in your life for as long as you need one another." thus if a friendship ends it is natural and for good reason and (in my belief) fate. "With every door that shuts another one opens~

Was it someone really close to you? The closer the friend was, the harder it will be. Little things can remind you of him/her. We think often when our mind has time to think about them. Go do something you enjoy, be with other friends. It could be as extreme as blocking this person from social media.. or not going to the places that bring memories. Maybe there were things left unsaid.. regrets.. If that's the case, maybe you need to write a letter out and get it off your chest. You could send it to them. Or you can tear it up/burn it/etc as a symbol of letting go.

Engage youself into work and studies. You'll eventually get past those feelings. The more you work the more you stop negative thoughts.

A friendship that has ended is in essence a personal lose, whatever the circumstance. This means there are many emotions you may experience. Go through them, experience the loss, and in time the loss begins to full. This is a natural part of life, and we naturally go on to make new friends. The important thing is that we have people around us who care and who can reinforce our positive attributes.

You can never forget someone who has been part of your life before, all you can do is wish them the best and move on.

That is tough, some people would just say forget about it, easier said then done right? You guys probably had great time together, laughs, irreplaceable moments, for me to stop thinking I need to create other memories, or try a different place that I´m used to or will make me remember this friend.

You know , its not necessary that the end of something means it should go out of your brain completely. Everything that happens in life like the end of any kind of relationship be it friendship or love , it happens because it teaches us something . Not everyone comes in our lives to stay . Some people come to teach us something at a particular point of time so the lesson learnt can build us stronger for the future . Thats why certain relationship comes at a particular time and then goes away . It doesn't mean we have to hate and forget the person who was involved in it but remember the lesson u received through that relationship. So incase of your friend , maybe it wasn't meant to be forever but for a phase of time and he/she came to teach you something that will help you in your life . Even if they did a wrong thing you can hate them and at the same time be thankful because if they hadn't come to ur life , maybe you wouldn't have been able to stand stronger as a person as you are now . Be it good or bad , all lessons build us bit by bit. So what you ned to do is take the lesson to remember it for the future and let go of the past . Take it light-heartedly thinking everything isn't meant for ever and some people just come to make a few chapters of your life and not write the entire book . Then you'll see its not too difficult to stop thinking . Cause at the end of the day its not important to forget but rather to learn letting go.
