I think ending your life so early on is a reckless decision, and one someone should never resort to. That being said, I have struggled with depression and those very same thoughts myself in the past. Last year was VERY taxing on my mental state for so many reasons and the thought of killing myself popped up several times. Of course, no one ever knew about this since I kept it to myself. What kept me from doing it? Well, mostly because there are many things I have yet to experience. I'd never get to meet the love of my life, have a successful career that makes me proud, get married, raise kids should I have them and watch them grow. There would be many things I would miss out on that a lot of people enjoy, and even speak highly of. Not to mention there ARE people that love me despite whatever I tell myself. The same applies to you. Sure, I might not be your family, and I don't even know you. But none of that matters to me. All human life is precious imo, and that includes yours. So I may not know you, but I'd be a little upset if you gave up here. The future holds many possibilities, and your life has just begun. You have a lot of things you haven't experienced, and while you think no one appreciates you now, that won't hold true forever. High School/College is a very small part of your life. Life will always test you, but remain strong and the trying times will pass and you will be a stronger person afterwards!
