im 16 yrs old, weigh 105 - 108 lb and am about 5ft 5in. for a few years i've had quite bad depression, and have self harmed a huge amount. im on medication and seeing a therapist for all that. i've always thought im fat and recently i've begun to engage in about 3 hours of exercise per day. i barely eat anything, usually small cereal for brekkie and half of dinner, or not even that. im determined to lose weight. i feel its the only thing i have control of in my life, coz im so desperately unhappy and empty. i hate my body and myself immensely. is this just a part of depression or another form of self harm or an eating disorder, or nothing.
