Depressed and can't feel happy about anything anymore?

I'm actually younger than you,so it may sound a bit weird giving you advices on this but.. Why don't you try talking to someone?Like your parents.Believe me,they would know what to do and it's much easier when you talk to someone.Go out with your friends,relax and enjoy life instead of just standing home, watching TV and be all alone.I understand you,'cause there are times when I feel all alone & like nobody ever cares about me,but this is ridiculous.If you have a family and friends,that's the best gift given from God and you'll always find a support on the ones you love.I hope this helped,someway :)
