Telling my school I'm depressed and their reactions...?

I think many people face the same problems as yours.It's a normal phenomenon.What you should do is to be relaxed,for example,you can take a travel when you have time,even with your friends.Making some good friends is good for us,friends can listen to our emotions,give their hands when we need help.Don't be too nervous and tired.Go out to see the world outside!
