The secret to getting over a relationship is opening yourself up to the pain, letting it run through you and sitting with it for a while.. don’t try block it or replace it and It will fade.
I found some YouTubers that do therapy type videos very comforting. Check out Heidi Priebe and another channel called actualized.org.
I found it better to be watching and trying to understand / heal than wallowing in the pain. I hope things work out for you
