Concentration

Please, whoever is reading this blog of mine, everyone - yes! you who is just reading this - please could you tell me how you concentrate and stop your mind from wondering off when you study?

I'm so so stressed with how much I need to know for this exam, yet my mind is still wanders off elsewhere and think about useless things. Yes, emotional things that I should not think about.

I know I shouldn't think about these things but my brain just does. I've thought it through, I know what is important and what is not, I know things can't be forced and I know dwelling on it is a stupid thing to do. I've tried to block it out for the past couple of weeks but nothing is working, I'm getting more stressed and upset than ever. Today I even so nearly went to buy some cigarettes. I'm desperate.

Please, someone just crack open my skull and take that part of the brain out so I won't think about this crap ever again.
