A brief summary of my story (tw in beginning)

Trigger warnings; scratching, digging nails into skin, cutting, crying, lying. I dont go into graphic detail about any of the things listed but please be safe.

I started self-harming when I was ten. I remember scratching at my arms and loving the red marks that i left. I remeber regretting it once i got home. I remember no one noticing what i was doing even though i was in a puplic place. Then when I was eleven it became more frequent. My mom noticed a red bump on my arm from where I had dug my nails into my skin, I lied and told her it was just a bug bite I had been scratching at. I didnt leave scars until last year when i took it too far. Then 5 days ago i lost control and i cut. Once i realized what i had done I started sobbing. It took 4 days for one person to notice a cut. I lied to my mom again. I dont know what to do. i havent told anyone and im scared to. I'm scared that they wont understand. im scared theyll treat me different because of this. I'm scared people will think I'm faking or doing it for attention and wont believe me cause im young.
