I am an undergraduate student in mathematics. My academic performance is really good but many people tell me "you are too stressed up", including people who know me for a few weeks.
Due to some serious family issues the last few years have been hell.
As the time passes everything is returning to normal but the professors who don't know about those events might think this is how my personality is.
I am going to ask letters of recommendation from those professors for a graduate school application. Do you think this will negatively impact my application? What I can do about it?
edit: It's just the air around me. Some professors mentioned this: "You are too tense, don't worry you will go alright". Not sure how to explain this better.
