I can not relate to "cutting" but i too have read or seen somewere that it is a way for the person to relieve themselves from their pain, by "cutting" and then feeling the relief through the sight of their blood. I also read that the risk of getting an artery is a risk that satisfies the person's feeling of worthlessness. I don't know if that fits in with you Tom i just hope you are or will seek help for it especially for the "cutting" immediately too, for your own happiness and safety.
I think I understand that level of boredom, not in a depressionistic kind of way but an ok kind of way through compassion and my readings. I know it is not the same thing, i am not saying that, I am merely trying to grasp the problem in the best way i can.
To Peters and his message i want to take the opportunity to say thank you for making me realize that if a child feels that bored but still isn't showing high grades or test results, that actually isn't under-achieving, it might be a sign of a high IQ level or some sort of capability to learn more if given the chance, tools. I know that's arrogance, but if you exclude my arrogant attributes (they are not even justified, i am kind of stupid

) maybe thats a sign of that child not being in the right program. (The school reference being a metaphor).
I believe we all have special skills in some level, i think i read somewere that.
Anyway however well Peters reference fit you i am now going back to the boredom. To my understandings it is like an itch under your skin and because ocd isn't depression is not like the gloom of a dark room but an unbelievable painfully boring feeling were everything is moving, Not still, but in the wrong colour, grey and that the boredom is only inflicted upon ones self which helps evoke a panic fear evolving around helplessness, the feeling of the boredom not to ever go away.
Yes i know that this is what boredom is but to the extent that it almost feels like a short depression, melancholy, but it isn't and often, now that isn't very "normal".
The only way you could compare this with the kind of boredom your describing which by the way, the blind shuts are they there because you are ashamed or feel guilt for people to see you in your room? because you can have curtains for that, is by comparing the helplessness without origin. I have read about a lot of people who have gotten over that gash awful feeling with medicine or counseling. I don't believe in subjecting your self to your objects of boredom, or stop rationalizing, that is to trivialize your ocd habits and go "so what" because i believe that, that would leave your feeling undealt with.
However i can't imagine how avoiding people wouldn't add to you're feeling of boredom? Maybe that is one of the reasons, at least a shallow one for your sleepiness. I know i am acting as i know what the heck i am talking about :-\ but i really just want to help

.
I Don't think you should feel guilty around your parents but talk to them and don't try to make your self unbored around friends in school, have fun (even though that's the most commercial jingle i have ever heard and still i am the one to blame for that writting).
