So . It really depends on the prof . Some of my more liberal professors are incredibly understanding , and I usually just send them Hello , My mental health has been pretty bad this week and that is why I ' ve missed class . Could you tell me what I missed and which assignments I may be able to make up ? Thank you , name . This won ' t work for the super uptight profs , usually , but it won ' t hurt to send the same email to them . They may not be understanding but they shouldn ' t be a dick about it if they are , they have no place in being a prof , and although it sucks to miss assignments , you ' ll have to ignore it . Also , talk to your classmates . You don ' t have to say that you deal with depression , you can just say you were sick and ask about missing assignments or notes . Best of luck to you .
