Why do I let self-harm control my life?

You do not let it, it just happens. It may be because you're experiencing a lot of stress in your life a the moment, which makes you go to self harm to cope.

Self harm is an addiction and a habit. Compare it to being an alcoholic. They need to drink to release tension, pain, to hide, whatever the reason. Eventually, their body demands it to "help". Same principle applies to self harm. When you cut, burn or hurt yourself some other way, endorphins are released into your blood to stop the pain and make you feel better. It's addictive. Some people might choose to cut, with no attempt to fight the urges. I'm not a professional, but I would say it's the same reason. It "helps" in some way. My advice to you would be to talk to somebody, and perhaps consider some counselling to help you overcome this.

Because it's the only way you cope with life, the only thing that you think understands you and takes the pain away. Or it may be because you prefer it. You may not think that, but you really do, you like the relief it gives and when somebody suggests getting a hobby, and you've tried that desperately but it never works. It's just not as good as cutting. And that's why it's hard to stop. It's an addiction.

I don't know. why did you? well, self-harming lets your neural system to produce endorphin and adrenaline, that literally makes you feel calm. or maybe the pain. It's just different for everyone, depends on a lot of things

self-harm won't benefit us in any way , the mistakes , the losing of persons who we love , or losing a big chance , won't back by self harm ..

Self-harm can become addictive and as it comes an addiction it comes harder and harder to quit. So it may seems that it controls your life because you can't stop and it has an impact in many parts of you life but as any addiction you can overcome it.

It's an addiction, just like drugs or alcohol. Few people know and understand that. I would recommend speaking to a professional about this extremely serious matter.

Because you become so addicted to it, it becomes a daily routine. And therefore you let it control you because there is no other option you want to find.

Because we're scared of change as well as the way people view us. We let it control us because we need a relief from the emotions inside us, so that they don't control us.

Self-harm is a form of control. We all want to feel things- and when you are coping with depression or anxiety it feels like you can't feel anything. Self-harm provides a new sensation other that the numb feeling of day to day life. I can tell you that self harming is just a vicious cycle- don't deprive yourself of the wonders of this world by limiting yourself to things that bring you pain. There is more to life than pain!
