How can I stop Self Harm if its the only thing that's keeping me from my anxiety?

I've found self-harm to to creates a physical pain to numb out the emotional pain such as the anxiety you are asking about. I think the first step to stopping the self-harm, is to begin to identify what the anxiety is about, and then finding other ways to cope with the anxiety. There are a few ways people cope with anxiety. A very helpful way is addressing our mind set and thinking (such as negative thinking, all black or white thinking, or waiting for a catastrophy to happen, etc.) and starting to address that thinking to take control of it so it stops getting us more anxious. Another thing that can be addressed is looking for things to do for distraction. This can help for both anxiety and self-injury. There are tons of things - from very active activities (aerobics, dance, hiking, etc.) to less mobile ones (arts, crafts, reading, visiting a friend, etc.). There are some websites that address self-injury that provide various ways of coping with distractions. Also, if you haven't already, consider talking to your physician. There are medications available for anxiety that is significantly intensive and can be prescribed on a regular or as needed basis. Don't be afraid to use online support groups, and find a listener you are comfortable with who can help you sort out the anxiety side of things and support you in your journey of stopping the self-harm.

Anxiety isn't always a bad thing. For example, if you are walking on a dark road and someone strange is following you, if you have this anxiety, it means you understand what's going on. So, you need to start thinking about adjusting this anxiety and start impugn it.

Try using a marker or pen to draw on places where you feel like hurting yourself. Keep doing this until you do not feel the desire to cut anymore.

If you aren't already, try and go to therapy, it will help you so much with your anxiety. You need to find another coping skill to deal with your anxiety - try yoga and running for stress relief. When you get the urge to self harm, try squeezing ice cubes or snapping an elastic band against your wrist or drawing with pen on yourself where you want to harm. Best of luck with everything, you can and will get through this.

Try to focus on other alternative other than self harm. Maybe try doing something that can makes you feel better.

This is a hard question to try to answer. Responding to one thing that you wrote; "its the only thing that's keeping me from my anxiety" - are there any coping mechanisms apart from self-injury which might help you deal with your anxiety? There are no "right" answers to that question but *your* answers to it are what matter.

I had to physically restrain myself and removed all objects that could be used out of my area. I found that instead, a slightly better alternative was Snapping and elastic band on my wrist. However this doesn't address the underlying issue, but it is a good short term prevention.

There are alternatives to self harm. It may seem that self harm is doing you good, but you need to realise that it is damaging your body and having a worse effect on you physically. Depending on the way you choose to self harm, try and find something else to do, which will not have the same physical effect but could help you emotionally. Always remember why you are wanting to stop self harming, keep a note hung up in front of you as a constant reminder and experiment with other means. Talking to someone, writing a journal of your feelings, doing things symbolically (e.g. if you cut yourself, try using a red pen instead as a symbolic means rather than doing it). There are many alternatives on the self help guides on this website, have a read through those too.

Try to find ways in which you can let go of the feelings that cause you to self harm, without having to hurt yourself

Self harm is never the answer, it only hurts you physically and doesn't soothe you mentally, try the butterfly project! :D
