Hi, I used to sh. I have stopped and haven't done it in a few months.
I made sure to clean my blade after every ''session''. I just used water. It's not the best but I recommend cleaning your utensil.
I put a plaster or a gauze on it. To prevent my clothes fibres from entering the wound and infecting it.
Please never use tissue unless it's all you got. The material in the tissue will break off and might infect the wound.
Don't forget to have a safe place to do it, you don't wanna get interrupted.
Here is a resource I want you to use.
This is a site where you won't be judged or shamed. Safety & harm reduction is encouraged here
selfharm.pics
TW: it is a self-harm site but I suggest you read the material there, on safety.
I'm not gonna try and say stop doing it because I know it's harder than it sounds. But I do regret cutting my thighs because if a person ever saw my scars they would treat me different/ think I'm weak.
Best of luck with it. Stay safe!
