I have no idea, but here are a few brilliant suggestions.

1. Set up as many obstacles as you can between you and your behavior. Wear a beanie, wear a wristband, wear gloves if you can, etc.
2. Wake up. Stop zoning out. If you say it's too hard, I say that's BS. There's a point, I know, that you catch yourself but say "f it, I'm doing it anyway." You have to have discipline. "But it's too hard." Discipline isn't something that comes easy; you have to force yourself. No one in your situation finds it easy to stop.
3. Redirect. Come up with something you do that helps you calm down. I would suggest mindfulness, which means paying attention to what you're doing, and how agitated you feel. Rate your level of agitation on a scale of 1-10. Try and let that agitation exist without trying to resolve it by pulling your hair. The longer the better. This would be a good time to take out your beanie or headband if it's not already on. If you're totally overwhelmed (I'm talking a 10, and only a 10) then go do something else. Go to the bathroom.

Life doesn't blow. It's just a skill that you have to learn. It takes time and everyone, including me, has problems. It's your job to work with your issues. You need to start building self-discipline though. Your agitation will be fighting against it, but you need to make a REAL commitment to yourself - not to me, not to your friends, and not to your therapist. It needs to be personal and it needs faith (in yourself, no one else). As long as you see your behavior as a viable solution to your anxiety, and as long as you see it as more powerful than your will, you'll lose. Realize that (1) it doesn't actually help your anxiety in the long run - probably makes it worse (2) you've been hurting yourself over and over by running from that feeling and from yourself and (3) that you CAN conquer this and really make your life better (hope). Then you can start unraveling this biyatch.

I don't post here a lot anymore, so if you want to contact me, you can email me @ edahn.small@gmail.com.
