Dear @Lee82
I'm sorry to hear you're really struggling with this intensity of emotions. It sounds exhausting trying to manage it moment to moment so I'm glad you're reaching out here for some extra support.
@saltandpepper it's really wonderful to get your experience and wisdom about what self-harm has meant for you over time, and that your knowledge about yourself and your triggers increasing, and learning different coping methods has helped you to self-harm less and less.
Here is an article about self-harm that might be helpful, it talks about building up strategies to delay, distract, breathe deeply, or divert, but anything that you find soothing or stimulating could be helpful.
There are also people to speak to if you want to distract or connect with someone on the phone to talk about what has overwhelmed you:
Lifeline: 13 11 14 or Crisis Chat
Suicide call back service: 1300 659 467 or online counselling
Samaritans: 135 247
And if you are going to self-harm, I would reiterate that your safety is highest priority. Make sure you get medical care if you need to.
Take care
