Everyone in school thinks I am bitter. How can I change their minds?

Possibly there are options to emphasize your non-bitterness -- but ultimately, the opinion of one person, multiple people, or 'everyone', regardless of their relation to you, does not necessarily define you. It's hard when people are putting labels on us that just aren't true, naturally we want to defend ourselves, but in the end, we cannot control what other people think. Your opinion of yourself is really what's important -- and you don't think you're bitter, which is awesome. You know your truth and sometimes that has to be satisfying enough. It can be exhausting trying to change other people's opinions; it's like inadvertently living for other people. It also seems improbable that 100% of the school really thinks this way; surely there are people who have neutral opinions, or some in the school who don't know you yet to form an opinion, and maybe some who have good opinions of you! Who knows for sure? People will come and go, but you will be with yourself forever. Hope you find some peace. Be well and good luck!

It depends on who they think you are and why they do so. If they think you are bitter when you even aren't doing things that make you seem bitter in general, then maybe you cant change their minds even if you tried to change yourself into someone else. It could be possible, but the only way to change their mind would be to be a person whom they think isn't bitter, and for that you would need to know what makes someone bitter for them by asking them. Personally, it comes down to being who I am and being okay with it, which can be difficult if I was thought to be someone not good, which isn't easy and understandably so. But maybe with time, certain circumstances or factors can make it easy to be ourselves and to accept that we are who we are doing our best, even if most disagree with us or cant see whom we truly are. I hope you can find a way out and have peace, I am sorry if this is giving you a hard time

You can never please everyone in life, you don't owe them anything so why should you prove anything to them? Being yourself is better than being someone you are not. Doesn't matter what they think of you, you live your life not them. Never let others write the story of your life.

do not try to be different, you have seen those people who seem fake dont be like that it will make you look more bitter, personnaly just be yourself if you are not bitter people will notice if you are bitter, try to be happier, dont try to change there minds just show them a different side of you if needed.

Smile. Be cheerful and energetic. When something bothers you, cover it with kindness and forgive it. Keep smiling and be mindful of your words and actions. Give people genuine but specific compliments on their qualities you like. Greet everyone. Stay Happy, and make other people happy by granting them small favors. Good Luck!

Try doing a little good deed everyday, like helping someone pick up their textbooks if they've dropped them. This action, no matter how small, will influence the person you helped, and maybe any bystanders that were near you. Next time that person sees you, they will look at you like the person you helped them pick up their textbooks or the person that gave them a rosin to rosin their bow in Orchestra, that really changes the person. Eventually a lot of people will see you like that, and changes their attitude towards you.

Maybe relax a little for even a few minutes and try to ask a few people why they think you're bitter. School kids/teens especially, cling on to one little thing and sometimes blow it out of proportion and it sticks with everyone. If someone tells you why they think you're bitter, don't take it personally if it's only a minor thing, and laugh it off, prompting them to relax around you too and think that you aren't so bitter afterall.

Ask the people what am I saying that is making them think I am bitter. How can I be more aware of what I am saying, feeling or thinking?

You can't change everyone, some people you can and others can be unwavered. So i guess that;s up to you. If people think you are and you think you aren't then do what you feel is best.

They say action speaks louder than words. If they think you're bitter, then do something that makes them think otherwise! It may not work quickly, but when time passes by, they'll surely notice how you're so different from what they think.
