Well, it's easier said than done, and processing guilt/regret is also easier said than done lol.
But hearing it a lot of times and telling yourself a lot and pretending someone else you love very much did the same thing and how you wouldn't think nearly as badly of them for the same thing, helps.
Much like I ignored reddit usernames in the comment section, I tend to ignore which instance a post is coming from while scrolling. So I subscribe to all the relevant ones, and just scroll from my "subscribed" in my instance.
