You are the strongest, most important person in your entire life. Life has a bunch of highs and lows, but no matter how low you can feel, just remember that there's no mountain to tall to climb, the bottom isn't the end. The only way you know there's a bottom is if there's a top that you can climb right back up.
Take time to look after yourself, trust me, nobody ever wants to die. I know someone who was very close to following through, and they regret every moment of that, so believe me when I say it's not worth it. And I can say that they are a much stronger and powerful person than they have ever been back then. So please, don't. This isn't a "we don't want a suicide on our hands situation", we're telling you this because you deserve to live your life out to the fullest. You are great, powerful, and you can do amazing things in the future. Life might be utter **** now, but that is never, EVER, your fault. And that goes to anyone who ever completates suicide in this thread. Please, look after yourself, talk to a therapist or call a hotline; they don't read card, they're specifically trained to help you climb that mountain, not just show you the motions. Most of them have been in the same place at one point of their life, so they're understanding, very patient, and will help immensly.
