(Also we listen and we don't judge, I lost motivation in 6th grade so it's a little empty, so you should go to 7th fr fr)
6th Grade was a rollercoaster of emotions, I gained friends I unfortunately lost friends. You get to meet amazing people (especially Mr.Garcia!) and have all new experiences. My advice, don't worry too much! As I unfortunately had to find out the hard way, focusing on just your school work is just going to make you stress even more. So just spend that time with your friends! 6th grade is a chance to try new things even if not everything is good.
