Am I depressed?

Ever since I started freshman year I had trouble about how my body looked. I began skipping meals and often binging at night. I also became very obsessed with my grades. I didn't want to go to school anymore and didn't want to live, I saw no point in it. More recently, this summer I was sexually assaulted by one of my best friends and ever since it has left me in my lowest place as I feel worthless and don't see a point anymore. Am I depressed?
