Hidesad, you are not a fool or an idiot! I'm sorry that you have to work with someone so horrible who has made you feel this way. Im a bit like you at work, and find it very hard to say no when im asked to help, i get afraid that if i say no then they wont like me or something, and i freak out at the thought of someone not liking me! When someone like that asks for help now, i just say that im reeally busy, but if noone else can help them that i will if i have some time spare. Maybe that sort of reply would work for you? Sending big hugs, J x
