I harm myself on purpose. I never do it because I need to cope, I do it because I like the pain and like to have something on my body. I know I should stop, but I don't want to. Why is that?

You don't want to stop harming yourself because you believe that you deserve it when you do not. Coping by punishing yourself does not help but rather creates more complications. Remember that you are beautiful the way you are and you do not need to harm yourself to feel better.

I am asking that same question. That’s why I do it. I have no clue why, I think it’s the endorphin release in your brain

that would be an addiction. try to break your addiction with some techniques like watching movies or maybe going out with people more.

We often find ways to take the edge off of things. It is our escape and our way of calming down. Unfortunately, not every way is healthy. There are some alternatives to self-harm, such as drawing on yourself with a marker.

This could be because of a self-destructive behaviour manifesting itself as self-harm and possibly other self-defeating, self-destructive behaviours. You may be looking for a way to vent in which case there are far healthier options available. If you feel the need to express it using your body or on your body because maybe you feel like expressing the marks that your suffering is leaving internally externally on your skin etc. You can instead choose to express it by drawing on your hands using something indians call henna or by taking care of your external self by formulating new beneficial habits that are good for your body. With the latter one you could be expressing a resolve to meet every trouble with equal stubborness not to allow it to get the better of you.

As someone who has experience with self-harm, I know exactly how you feel right now. Stopping self-harm is difficult because it can be addicting, whether or not you self-harm to feel happy. The fact that you know you should stop is already a big step in the positive direction. Other steps that really help in stopping include speaking with a therapist regularly and finding a less harmful activity to do instead when you feel like self-harming.

You are experiencing pain and you dont know where it's coming from. You harm yourself because you can see where it hurts.

Maybe you need to feel the pain, maybe it helps you to feel you are alive, maybe is better having physical pain than emotional pain

You've done it for a long time and even if you don't do it to cope, you still feel the need to do it. You like the pain and maybe that's someting that makes you feel secure. That's one if the only things that stays the same.

Self harm is a very complex thing, and that is coming from myself as a person who used to struggle with it. I wish I could give you, or believe that others could give you, a magic answer. However, because it is so complex and each of us is unique, it may be worth finding a trusted person who you can talk to in depth about what you are experiencing - Perhaps a counsellor or other therapist - So they can help you through your journey of discovering the reason for this and a way that works for you to solve it.
