I'm a 1st year senior highschool student in Japan and have lived here for about two years.
Sometimes when I'm with my friends they don't talk or look at me as if I don't exist and I ask myself if I did something wrong. I've always been nice to them even up to this day. So that's why I asked one of my friends if I did something wrong to him/them in the past (and if I did I would be willing to say sorry).
He asked my why I was asking this kind of question and said that I'm just misunderstanding. So I want to say to him "Something doesn't really feel right at all". What would be the best way to express this in Japanese?
