Is 13 the hardest age for a kid
If not, there are suicide helplines you can call anonymously to talk to someone. It is hard to see the answers to your problems when you are depressed, but sometimes someone else CAN see solutions or ideas to help you. Other options are ministers, family, friends, teachers,etc..
I hope you can find a way to allow yourself to trust someone to talk to them about your problems. Everybody has problems. They may be different problems, but they still have them, no matter how much it looks like they don't.
Tennisluver,
You need to be speaking with that teacher, not spending your time asking questions here. We cannot help you, but only encourage you to do what you know is the answer. That is to approach and tell your problem to your counselor, teacher, parents, or another adult who will listen and help you. There are many ways to deal with depression, such as medication, talking to a therapist, etc. You don't have to live this way. Take that first step and talk to an adult who will listen to you. Do it today, you'll be glad you did.

Im three years older than you and 13 is a tough age. I was the same way at 13 but i spiraled into self mutilation, drugs, and lieing. The depression can make you turn anyway for release. You don't want to be like how i was over 12 tapemted suicides later im still alive. But, many people i know weren't so lucky. Doing what i did will make things worse insted of making the better. Go talk to your counsler if you don't want to talk to your mom. They will be so thankful that you came to them and that they caught the depression and can help you. Just tell someone they can help. I have been in therapy and it's done wonders for me. I hope it would be able to help you. Good luck and please tell someone.
