Finish college with a 3.5 GPA.
Spend next summer interning somewhere far from home.
Once you’re done with college, move far, far away from your parents. When they berate you for moving far away, THEN tell them that you heard all of the mean things that they said about you.
I’d start exercising a few times a week; your height/weight aren’t out of line but it’s good to get into good habits, since once you’re working and aging, weight will creep up on you and it’s harder to get in the groove of a fit lifestyle once you’re older.
