I'm sorry for that.
You're young, you live has just begun. You still don't know your potential, much less other people. They don't know everything about you, so, how can they judge you? Everyone fails at somethings, everyone makes mistakes. Specially when they are young. You're not the only one, dear. You weren't even the only person suspended. Take it easy on yourself for now.
I've wanted to kill myself too. Any small error would make me feel hopeless and unvaluable. And I felt attracted to those thoughts. May sound weird but sadness is addictive, so we are easily drawn by them. It's part of being human. But I started to question my suicidal thoughts, Is this really right? Am I that bad? Looking back, I'm glad I ignored that autodestructive bias and tyed hard to look at it in a rational view. Some good friends helped me a lot with it, too. But take care, some people are just toxic. Some wants to make onther people feel down just to feel better about themselves. Don't take them serioulsy, because this life is yours and they can't decide what you are. Only you can do it.
My mother and I argue a lot. Sometimes she treats me in a way that makes me think that she dosen't loves me. But on the other hand, she works hard to make me happy and took good care of me despite I being not a good daughter sometimes. So, I try hard not to fight her because this only makes things worse.
If you kill yourself, you will also kill a future you don't know yet. Things change, more that you think, though it may take some time. Be patient, because I definitely assure you, no pain lasts forever. Thing surely will get better, if you simply allow it to happen. It's not that hard, though sometimes it feels really awful and hopeless. But there's always hope, since people can change. Yes, even you.
I must say it, you're being hasty. With a good attittude, you can make everything better, even though some people may look down on you. You understimat yourself, because you can always improve, and also have a lot to see about you and this world yet. If you throw your only chance to prove them wrong, your only life, you may not know how good things may happen to you, if you just give yourself another chance. At the end of the day, things may not be so bad as you think.
Suicide is wrong and very extreme. Odds are you will really regret doing it. More than being suspended. Everything has a good and a bad side. You just have to see it. I like to believe in what dosen't kill you makes you stronger. Lift up your head, dear. Just keep living.
Thanks for hearing us. You seem like an awesome person, really. Honestly, I wrote this with my hands shaking, so afraid I am of you going.
