Do you see a therapist or something along that line? Maybe you could have them try to help you explain it to your mom.

That talk is never easy. Maybe start it this time with...
"Mom I had an issue my coping strategies were not enough, no matter what I did I couldn't stop myself. I am still getting better, but everything just became too much at once."
Or something along that line. Explain exactly what it was that made you do it this time.

I hope it goes better than her yelling at you, good luck.

I completely understand, is it so bad you have to tell your mom, or could you tell another trusted adult to help you? A therapist? Teacher? To help before you go straight to your mom

I do have a therapist, a good one at that, but I don't see her until Saturday. When I started this, I "lost her trust," (I say it like that, because she stopped trusting me before I actually did anything), and now I have to "earn it" back, by telling her whenever I do it again. I have issues with this because it causes more problems than it fixes.

Can you call your therapist? Sometimes they will talk on the phone and give you advice on how to speak to your mother.

My mother did that when she say my scars for the first time, "Where did I go wrong" " How can I fix this problem "what did I do to deserve this" From her actions I knew I could never tell her how much I use to cut or tell her anyting about it. I use to pretend that everything was fine, she still thinks it is. She was no help so I learned to trust no one. I have a hard time talking with a therapist because I couldn't trust my nother so how can I trust a therapist. I hope all goes well for you.

i think we can give you a great support system here...i dont know how this feels because my mom and i never "talk" about it...she sees my arms yet she doesnt say anything..shes in denial and doesnt want to deal with my cutting...granted, i'm 40 years old...still she looks the other way...i think once she said don't do that anymore...at least she recognized...anyway, i hope your mom will soon understand that this is your coping mechanism and i believe an addiction...i hope you both will come together so you can start healing soon

Sorry, some people just don't understand. :( That's annoying and frustrating.
