For me my main reasons not to are
1) My family. Im letting them all down. My little brother saw my scars and burst out crying because he knew exactly what they were from. I made my mom cry. My dad just pretends like he has no idea whats going on so he doesnt have to accept that theres something going on with me.
2) Hospitalization.
3) Accidental Death
4) If you have self esteem issues to begin with the scars make then 1000 times worse
5) Lying to keep your secret safe
6) It doesnt solve anything
7) Its addicting
