How can I deal with being blamed for things that aren't my fault?

First see and hear everything they saying to you, do not stop them or interfere with what they are saying, I know it hard but listen and once they’re done, if you know you have done this before but you didn’t do it this time, let them know that it wasn’t you this time and ask them if they have asked any else about this. If they still don’t believe you, keep eye contact with them and tell them with confident that you didn't do it, tell them where you were what your were doing, once you have confirm them that you didn’t then leave because you already know it wasn’t you and whoever it was they will slip up, but have to try not to do anything that you could be blame at. Like if you know you have done it before don’t it anymore and stay low for a while so the culprit could be easy found.

I can relate to that question as the oldest of four children, my parents blame a lot of things on me that I have no part in. Sometimes people don't see the truth so we have to suck it up and just take in the criticism but if we do our best to be our best selves and give them no reason to blame those things on us, they will soon see that those actions were not our fault. It also might help to ask them to explain why they are blaming you. If they have a reason, there must be a way to disprove it if it really isn't you. If their reasoning is illogical, then just give them time and show them through your actions that you are a better person than they are making of you. :)

Try and talk to the person who blamed you and try and reason with them. Try explaining you're side of it. Don't get flustered and get mad. People tend to be more understanding when the conversation is calm and not tense. If that doesn't seem to help the issue, don't forget that You know the truth and that's what matters!! They might not be able to understand it from your perspective, but you know the truth and that matters. Don't beat yourself up about what others think they know. The only people that truly know are you and anyone involved.

You can try talking to a teacher, parent, older sibling, or someone older who knows what your going through. And remember to always tell the truth even if they don't believe you. It's honestly honesty that gets you to the top and helps you through life. If someone is blaming you for something you didn't do you should also try to show them proof that you had no part in it. Or find witnesses. Even ask someone to just believe you might be enough to turn someone else's perspective. Now I need to get to 100 words for some reason so there lol.
