I’m not sure what’s happening to me

I’m a 17 year old rising senior and I have been doing so well academically. I’m a fanatic about grades and put a lot of pressure on myself to do well. I’m taking 3 aps this year and my grades were great.<br><br>I don’t know what’s happening but I feel incredibly unmotivated now. I’m not doing my homework, I’m late to class, I’m not showing up to tutoring and I’m just doing poorly. I’m also having trouble sleeping and everything is making me anxious. <br><br>My grades have never been bad but now I’m averaging around 86 in all my classes. I know this is still good but it’s not what I’m used to. I’m not getting good test grades either. I just feel really unmotivated and lazy and I don’t know why. I’m going to turn 18 this month and I’m not sure what’s happening to me.
