Must be tough.
I have some worse bullying stuff. There are these two stuffheads who are always calling me gay/friend/someotherstuff.
Anyways, one day they both call me a friend. And the motherloving teacher is STANDING WITHIN THREE loving FEET OF THE CONVERSATION and she does NOTHING. Anyways, I'm sorry for what you're dealing with.
stab them with a loving sharpened screwdriver, stab them right in the lung.
Freek, I assume you're acting beta at school. Right now, that doesn't really matter since you're like 13 or something, but it will in highschool. I would assume you're also going to be with your middleschool group in highschool, so it would be best to make a better image for yourself. If someone calls you a friend, defend yourself. If someone steals your computer, take it back, ect.
as for the teacher stuff, i've never been good at remembering stuff myself. I find it better to have some sort of agenda to write my stuff down in. I also do well by keeping my homework assignments in my book rather in some sort of binder. It doesn't do too well when i have to go back through the pile of old work and handouts in my back pack, but it works well for homework.
