Hi LittleForgetMeNot,
I know what you're going through because depression has caused me to miss quite a few classes as well. I wasn't depressed in high school but it hit me in my first year of university, and by the end of that year I was attending maybe one class a week. I had to get special dispensation from my department to let me continue in my program, and although I try hard to make as many classes as I can, the depression still gets the better of me sometimes and I just stay home in bed instead. Because of my absences and isolation, I haven't made very many friends here either, so I understand how lonely it must be for you. Lynn P gave you some really good advice about trying to get through. I would definitely talk to a teacher, student counselor or your principle to explain what's going on. They may even be able to offer you some assistance. The only other thing I'd suggest is that you keep in mind that high school doesn't last forever. It's a finite amount of time, and it may be tough but eventually you'll be out and you'll be able to do something else with your time. When you do dread going, try to remind yourself that this whole high school ordeal is just temporary and doesn't have to define you for the rest of your life.
