I fucked my exams due to lack of motivation throughout the school year. Talking with a friend made me realise that my combination of poor eating habits, struggling for motivation even in tasks I would enjoy (like playing games etc) and the obvious lack of doing any schoolwork for the past 7.5 years may be severe depression.
Never talked with someone I know in real life about any mental health issues I have. But tomorrow I have a student support meeting and I'm going to explain everything and hopefully get referred to mental health services.
