Yes, it can be hard even when you have left, what happened, happened, and traumas are always in your mind. For me, I tried to feel more controlled by reading self help old and listening to music I love. When you control what you can, such as what you do, it helps you to gain the sense of control. Professionals and supportive ppl help too. Just dont give up and continue reaching out and do what you can. accept that you’re going to feel bad sometimes, and wait it pass and it will. Be patient and kind to yourself.
