I agree with you. I know they didn't like being ghosted, no one likes. But I also know I was holding them back. My friendship was toxic and nowadays they're in college, have new friends whom they go out and have fun with, have SO's, have jobs while I'm stuck in the same city, unemployed, with literally no friends. If they were by my side, they'd be on the same boat. I know "it's for your own good" is a shitty saying but in my case I believe it's true. Their lives are waaaay better than mine, how can that be bad? I don't think people are missing much for not having me as a friend. And yeah, I did it for myself too. I was unable to manage those relationship and thought it was better to let it go.
