Hello there!
I'm so sorry you're hurting so much! Can you share with us if you've done anything in the past as far as professional help? Have you ever been in therapy or tried a medication?
I can tell you that while depression stinks, you don't have to just accept it as it is, and prepare to always feel so badly. There IS help for depression. Please reach out to someone for help. You don't have to fight this alone. SO many people live with anxiety and depression every day. You have your whole life ahead of you, you can do anything you want...the future is at your doorstep. Once you get some help for the depression, you won't feel so uninterested and unmotivated.
We're here for you, please keep in touch. We also have a teen depression forum if you want to check that out as well.
