Recreating your entire home so it feels safe, and like a place where you can build new memories? Is a big project. I’ve watched a friend have to do this after she was assaulted in her home.
Maybe start small. A single room, or a corner of a room, or a space in the yard. Focus on that small space, and ask yourself “What would a perfectly calming, soothing space just in this corner feel like?” And recreate that place so that it feels new, and somewhere in your house that is about safety and calm. Then make a point of going there occasionally with a cup of tea or some body lotion or something, and do 5 minutes in your calm space.
The rest of the house can be a project that grows from there.
It doesn’t need to be expensive. Repainting the walls is a big job. Posters? Are a small job! Swap furniture online to avoid costs if that’s an issue.
There’s lots of solutions to this. I live in a studio, and my patio is a space that I keep junk free and luxurious so that I can always go there, and just sit and breathe, and know that I’m in a space that I have created and recreated over time to be my own tiny corner of calm.
Just a few ideas:)
