I can't speak for others, but I don't think I have any difficulty understanding you, after seeing several topics you have posted in. However, I do think that you sometimes have difficulty understanding yourself or the gravity of situations that you might create, and might therefore be misguided at times. That is somewhat natural when you're still young, but learning from bad experiences and not repeating the same mistakes a lot is also a major part of growing up.
While I am not one to accuse you of being a liar, since I have no proof to back up such a claim, some things you do say seem overly dramatic. Now if you were one to tell lies just to gain attention to yourself, you would be entering pathological liar territory, and I hope that isn't the case, because that's a very unhealthy path to go down. But to a lesser extent, there are also exaggerated truths, also for the sake of adding attention, and not in a positive sort of way. You mention getting bullied, yet you yourself mentioned engaging in similar behavior. This is hypocritical, as you are choosing to take a low road instead of a high one, whether it is to fit in with certain groups of people or not. It's not unusual for the bullied to also be bullies. If you don't listen or remember much of what other people say, I hope you can remember this, as you lilkely won't regret it later:
The best revenge is living well.
Try to focus mostly on things that make you happy, that isn't clearly at the expense of others. If you have a certain talent or hobby, focus a lot on those sorts of things. If that changes over time, which is quite common, that's fine too. Interests can change, as people change.
