Dude. Chill. Of course people choose what to believe based on whether they like someone on not. It happens with celebrities and politicians all the time. And you mentioned that your supervisor plus 3 other people, plus your cousin, plus other students asking you why you're beating your own dick with your accomplishments. That's not 3 people. I could be wrong and the people that asked you why are the same 3. If that's the case, then sorry. And also, obviously I wasn't making an assumption about you talking about yourself if students are telling you stuff like that. It's not a matter of whether it's true or not. They believe that.
And I was referring to your original post. Not your reply to me. I was just saying, that if you wrote all this wall of text post asking for advice then that means that you care. Nothing more. Nothing less. I wasn't acting superior. And I told you why they do what they do. You just don't believe me. They simply don't like you so they choose not to believe you.
