How do I let go of pent up anger towards an ex?

I grab a notebook and write out all my feelings out, it has to be a notebook too, there is somehow a difference between typing it and writing it. But I write everything I want to say to them and get all my feelings out, I say things how they are. I don't sugar coat anything. I know I don't even have to be nice about anything in what I write. But in order to let go of all of those negative emotions I soon after that get rid of all the writings.

Realize that anger is a poison that you are poisoning yourself with by choice. Whatever your ex has done to you, I am sorry that things happened like that, but you have to forgive him. You have to forgive him for the sake of your wellbeing. You are worth a lot more than this person valued you. Value yourself enough to let go of unnecessarly hurting yourself further while this person might be sipping cocktails at beach. Good luck!

Forget. You don't necessarily have to forgive, but block all contact from them. Write their name on a pillow and punch it. Take deep breaths, get fresh air, and just let go. Imagine this ex as a weight being lifted off your shoulders. Hope this helped!

Remember that forgiveness isn't for them, it is for you. Taking poison and expecting another person to die is a prime example. Meditation can help. Being mindful of when these feelings of anger arise and how to healthily cope with them is a great starting point. It always helps to talk with someone just to get it off your chest as well.

Don't bottle your feelings up inside. Talk to someone about your feelings, let those feelings out in a calm fashion. Try to engage your mind in things you enjoy and love, so that you can begin to move on and let go of those feelings of anger.

Focus on the lesson the experience has taught you. We grow from our pain and changing our perspective on the situation helps us move on.

Spend time doing your own hobbies, instead of thinking what it would be like if they were there, think of ways you can do something for yourself. Go to the park and read a book, take a trip to the beach. Spend some time on your own and do what you want to do

It is normal to hold grudges, we are human beings. Sometimes the easiest way for us to grow and let go is to accept that sometimes things just do not work out and mistakes were made in the past relationships, but you have to know that you learned something. You might have gotten to know your likes and dislikes better as well. So anger can be made into a lesson, and makes you a bigger person to let go as well and not hold negatives thoughts.

Personally, I found writing out a lot of the things I wanted to say to them, and then deleting it. Talking to friends, and removing any stimulus/memories of them from my safe spaces. Anger is hard to let go of, and while avoiding reminders of them won't solve everything straight away. it will definitely make the transition period of letting go much easier and you'll find yourself less focused on them/your anger.

Through great coping techniques! haha. One of my favorite ones when I'm angry at someone else is to write a letter to that person but don't actually send it to them. Write all your anger and aggression out on paper. Let your mind unfocus and ramble on. After you are done, take the letter and burn it. Let the anger and feelings burn away with the letter (but please be safe with fire!) It is important that you destroy the letter or throw it out. This shows that you are letting go of those feelings and allows no one to be hurt by the words. Hope that helps!
