Situations like these can be pretty frustrating. And trust me, from now on, it'll get better. I don't know how the education system works in the Netherlands, but in the region where I live, transition from junior high to high school is extremely rough. Personally I've never cared too much about school. I'll do work and stuff, but I wouldn't go to far in. But I do understand that at high school, it's pretty critical to do your best. You can talk with people and enjoy those moments, but you should manage your social life well with school. Understand that if you don't get into university, life might be a little harder, but it's not the end. But for now, try to get motivated. Maybe step away from electronics for a bit and focus on things like sports, clubs, etc. It'll help in the long wrong. So, yea, that's all I have to offer, good luck.
