"You were just a kid..."

Yeah my mum makes jokes about my past, and jokes about my sucide attempts like they were nothing. It does hurt and I dont think anyone who hasnt been through the struggles of SI will every understand why someone would do it. Your mum comparing it things like smoking sounds like her way to justify what was going, so it couldnt of been her fault. When parents find out about things like this, there natural instint is that it is there fault, my parents thought this and no matter how many times I tell them its not, they will always doubt that

Your Mom has found a way to rationalize your cutting so that she is not in anyway responsible and so that this is/was not a serious problem, just a normal part of growing up.

She is, of course, totally mistaken.

But it is most unlikely that she will never change her mind. She certainly won't if you push her on the issue. Let it go. Seek the understnding and care you desire, and deserve, elsewhere.

I've not had some of the same experiences as you, but I understand what you mean about being validated.
When my parents found out, they were very unsupportive. They went through my text messages and then began yelling at me and making me feel like dirt. They weren't concerned, they were angry. They were angry because I lied to them. Which is the biggest hurt for me I think of the whole time. My dad told me that I had to give up being close to God and get rid of him from my life, because no one who does this to themselves is anything like God. I also remember that night, I accidentally knocked over a glass and my dad scolded me and told me to clean it up. While I was down there, he stated "oh and don't cut yourself cleaning that up".
My parents also forced me into the car and they drove me down to the hospital to have me admitted. I knew the whole time that they weren't going to send me there because my dad doesn't like other people being involved in such a huge family matter. But my dad did it just to scare me and make me feel like garbage.
They weren't interested in what kind of pain I was in. They were interested in belittling me and interested in being angry.
They threw me into therapy thinking it would be a quick fix. I recall telling my mom that I had an appointment and my dad said, "Oh, I thought she was done with that".
One day I also had a spinter in my hand and I couldn't get it out. When my mom went to pour alcohol over it, I pulled back and I said that it was going to hurt so I didnt want her to use the alcohol, and she said "Seriously, this coming from the girl who cut herself?"
It's been painful.
Needless to say, I think we all have those moments where we don't feel validated or understood. My parents have never accepted the reason why I was cutting, nor will they ever. Which is why I put on a happy face, and quit therapy claiming some miraculous healing. I couldn't take the private pain anymore.
I kind of feel like your mom sees this as some sort of phase thing, or fad, and I can relate to you there, because my parents saw my cutting as just a phase. And they always reassured me that I was smarter than what I was doing etc.
I think we just need to keep telling ourselves that pain is real, and that it is also personal. We know it better than anyone other than God.
We have the right to validate it the way we want to.

I am very glad that you have found a way to get past this.
The comments people have already made are so true.
I struggle with SI, and I am also a mother of teenagers.. and I know that, whatever the reason, if I found out that one of my kids were cutting, I would feel responsible, however irrational that may be.
Your mother is relieved, and trying to make herself believe that it wasn't that bad.... I am sure she knows that it was really, but... feeling a failure as a parent is very hard to deal with. I think her response is fairly normal, but that doesn't make it hurt any less!

Do you have people that you can talk with about this? Her feelings are important.. but so are yours, and if you can't talk things through with her, try to find someone with whom you can.
Praying for you, sweetie

Hey Antonin...have you talked to her more about this? Maybe this is a chance for you guys to grow closer. It could be that she fears you might do it again or she could be trying to validate it in her own mind. Try sitting her down and talking to her about it, explaining it more now that it is in the past a bit so that she can understand more and get to know you better...she loves you, she just wants you to be okay.
