I have cuts on my breasts

College girl here - I have a few hypertrophic scars (dark raised scars) on my breasts from when I was deep in my SH/depression and no one knows about them or has seen them except me.

fyi I only cut there cause it’s the only place could cover while wearing a bikini

I was wondering - how common is it for people to cut their breasts? Has anyone else done it there?
