Well, what do you like to do? lets say if you like sports, go out in the open air and do it. What makes you depressed? Try defeat it, and you will realise the greatness that comes out of it :) stay happy and smile more. You can also save money since your so young and later go on a vacation to other country and exploring is fun!
Try to talk over your situation with your mother or father, another related adult, school teacher, or school counselor, whoever you feel most comfortable with. You should have some time to do some things outside your home.
Hello~Do you attend a church, is so, is there an opportunity to join a youth group? Do you do social media such as Facebook, I know it isn't the same as being with folks face to face, but it does help, there are so many groups there a person can join depending on what they are interested in. There is also an on-line Christian forum that has some groups for teens. It is called Christianforums.com.
