It's no secret that I'm very disliked because of 11 year old me (also stuff I did like 5 minutes ago), like I know I am really obnoxious, and I am a horrid person sometimes and I feel bad that people have to even be near me or read what I type sometimes, like I say the most annoying stuff and I regret it quickly after I say it, this apples to real life and the forum. I wish I could start over or just go back and fix it all. People think I know I'm being annoying so I keep doing it, no it's just me, and I can't stop being annoying, and I hate that I am, I try to be a better person but I can't, I always have to do something dumb to mess it all up again.
You should stop worrying so much as to what other people think about you. Firstly, it's the internet... You're talking to people who you are most likely never going to meet, it's a very different situation as opposed to people at school. And even then, why should you care as to what other people may think about you? You are never going to win the approval of absolutely everyone, no matter what you do. You're BOUND to annoy at least someone, and that's okay, you know? As long as you're happy and you're being yourself, not feeling like you have to try and have to hide behind some fake facade to win the approval of others, then that's what is most important.
Secondly, I'm not sure how old you are now, but... Seriously, we ALL say and do 'stupid' things when we are 11 years old. That's just a fact. As we grow up and get older we realise how things we said or things we did in the past are quite immature and perhaps ignorant but, that's okay. Growing up is really just a process of learning and experiencing new things and maturing at your own pace. Of course you might seem 'more annoying' or 'more stupid' than other members because the majority of people on this site are at least a few years older than you and therefore are more mature than you. Don't feel like you have to try and force yourself to grow up in order to win the approval of people on this site. Of course, be conscious of the things that you say, you know, just think before you post and stuff, that's just basic though really... If you think that you might say something that will hurt someones feelings or might come across as rude then don't post it, but that applies to everyone on this site really, that's just what I do.
And finally, stop thinking so negatively of yourself. You're focusing a lot on the bad aspects of yourself rather than the positives, and really, if you want to give a good impression to other people, it's much better for you to focus on the positives than the negatives. I mean that is much harder to do than you would think, but, stop beating yourself up over just being young. When I was 11, I said and did really cringey and dumb things and sometimes I wish I could rewind time to change what I did so I could rid of the memory, but, that's just a part of life. Human beings are not perfect and we all take time to progress and learn and mature. You're not obnoxious or annoying because of your age, at least that's what I think. People are just obnoxious and annoying because of their personalities, it's not because of how old they are. I am sure even by this time next year you will have grown up a lot and learned a lot of new things... You're still only young. Don't feel like you need to improve yourself for other people, just improve yourself because you want to.
Also lol, I guess, it just bugs me a little when I see a lot of younger members on this site making big "Apology" threads in Brewster's, like... You don't need to apologise! If you have personally upset someone then fine you can just VM them but don't feel like you need to go and say sorry to everyone on this forum for being 11 or for being 'annoying'... Tbh, most people just don't care at all, anyway.
tl;dr - don't feel like you need to win other peoples approval, just be you, you'll never be able to please everyone. Maturing and growing up will come with age, we all say and do silly things when we are younger, do not worry so much as to what other people think. ^^
Edit: ALSO AYSUH, I know that thread's closed, I WAS JUST SAYING.
