Oh, yeah, and I forgot to add a few more things. The bullying can have long-term effects and by "long-terms effects" I mean that fifteen years after the traumatic experience took place, you are still are suffering from the same sh*t as you were when it originally took place.
Also, it can give you a sense of non-reality of your life. By this I mean, that you do not know if your existence is real. You may have crises in which you don't know where you are or who you are. You don't seem to remember anything about your past, you don't know where you are going...I would like to think of an adjective that adequately describes that feeling but I can't find one. "scary", "nerve-racking", "tortous",...No, I don't think any adjective exists in our language to describe that feeling.
You walk around like a zombie not knowing what to think. You may even suffer from hallucinations similar to those that the main character has in "Jacob's ladder"(a very good motion picture, btw).
If you have been bullied, that can leave you with an enormous feeling of rejection. Therefore when someone doesnt answer emails, phone calls, etc. you take it out of all proportion and get into a state. You can start blaming people irrationally for not loving you enough. By this I mean, by them not wanting to do even trivial things with you.
Really, bullying sucks, as you may have imagined. And something has to be done. And to all those people who say that bullying is part of growing up, someone should beat the living *"#! out of them. J*sus fu*ki?g christ. All your youth down the toilet because of a handfull of bullies...
