how do you get motivated to do anything? im in online school; im 5 weeks behind, i never get out of bed, and my bones have deteriorated my flesh from the inside- it hurts to do anything. 

im 16, i dont have a job, i dont have a license, i dont have friends, and im severely depressed. 

How do you function / learn to function in society like this? How do you get motivated to do things you don't want to?
