I'm having a hard time motivating myself, help?!

Ever since 7th grade I have been having a difficult time motivating myself to do better in school. I'm now in the 10th grade. I have been getting poor grades - a few B's here and there, C's, D's, and plenty of F's. My mother yells at me because of my grades and says that I'm only doing bad because I'm lazy. I don't see it like that, though. I really do try hard to get myself focused and I have been having a rough time caring. I do want to get good grades, get into a good college, and get a good job. I just can't really GET myself to work for it. I have found sources of motivation before and they helped for a while, but they never last long enough. Whenever I'm doing well - something has to happen to completely throw me off course. Lately it's been more than having a hard time in school, I'm losing interest in sports and going out with friends. I haven't seen the need to get out of the house - it's always school, homework, and sleep. Sometimes I barely care enough to get out of bed in the morning, no matter how early I go to bed I'm always tired. I'm sick of being a disappointment. Do you have any advice.?Health Question & Answer
