Back scratching?

As far as i remember, this started about 4 or 5 months ago, One day i turned around in the mirror and noticed all these scratches on my back.. and i wondered, wow, how could all this skin be like that and i never noticed? So i started paying attention, and realized i do indeed scratch my back a lot.. it's not because sanitary problems, but because of stress.. When i stop scratching permanently for about a week, all the marks go, butif i scratch for 5 mins, it all comes back for another week or until i stop. During exams last month (high school), i found myself constantly scratching them while studying.. even during the exams itself,, whenever a hard question came along,, off my hands went to my back.. now that i'm all done school, i figured these would be 2 crucial months to recover and get my back healthy again.. I started working at a restaurant though, and whenever i feel uneasy with a customer or something, i end up scratching.. PLEASE HELP! how can i stop this terrible habit?!

Just stop it!

Drink more water to cure the lasting red marks which result from dehydration.

Sounds like you are OCD with panic attacks.

Take a chill pill from your Doc, Valium is wonderful or any Diazepam and relax!

Your paying for my eye surgery for reading that block of text. Anyway what you can do is maybe get another habit, like for me whenever Im thinking about something I sometimes frown and put my hand locked behind my head. Or I use on both hand the pointer finger and thumbs to make a triangle that I put over my heart. Just start a better habit and you will quickly get off that habit.

Simple, cut off your hands.
