I like the advice Miswimmy gave. It's about doing one thing, then one more thing. Today just take a shower. Then go outside and sit for a while. IF you have a pet spend some time with it.
It's important to get help. Depression is difficult to handle all alone. You need someone to talk to. Maybe you need a little medication. There are things you can do to feel better. Look up the article s on this site. This doesn't take a lot of energy and can help get your mind involved wirh something useful.
Just please don'f give up. Is there a counselor at school you can approach? Call a help line and talk to someone about your life.
Post here as often as you need to and we'll try to help.
I hope you feel better soon.
