Sometimes it becomes pressure for me that I always need to say ''Yes'' to everything that my friends ask for. It's doesn't mean that I don't want to help them or whatever, but I feel really bad about it. They keep wanting me do whatever they want, I mean if they want that I HAVE TO do that for them, they always want me to do like that all the time, even I say ''I can't''. On the other hand, I still cannot say ''NO'' to them as well, whenever I say ''NO'' to them I always feel wrong but at the same time I feel pressure as well. I feel like sometimes they don't respect my decision. I swear I want to be a selfish person sometimes, I don't want to be a tool for anyone that can be using all the time like that, but I don't know HOW TO SAY NO. Tell me if i'm wrong.
