Depression??

So I was laying in bed and I got a text from my mom and I was supposed to get a bag to sleep at my friends house. But my body and mind didn't want to get up so I layed there (not asleep just laying there) my mom came home and told me to get up and get the bag ready so I forced myself up and as soon a I got up I felt empty and I went to my closet and broke down for no reason. So now I'm confused on why I broke down
