I'm sorry about what happened D: While I can't help you, I recommend contacting a mod or admin about this! It's so sad your account got hacked and you got banned, but just hope things get better in these times! In the world we live in now, it's filled with evil people, like who ever hacked you!
It's okay! <3 I also hope things better in time, thank you.

This is very scary, indeed. I'm terribly sorry this happened to ye', Rita. Like DelightfulRevenge said, perhaps it'd help if ye' were to create a new account and leave that hacker to his own devices. I don't think changing your password would help, as ye've already stated that it would not work. Hh- I do hope this issue goes away. There are some nasty people out there, I swear.
I also hope your friends will understand the situation. It's rather awful what the hacker did to ye' and I'm truthfully very sorry.
Yes, that's what I also thought. But even if I tried to make a new account, it will take a long time I guess. And as of my friends, it's difficult because they're not answering me at all. So, I think that they have done something really bad to them like break their hearts. I'm trying anyway, because friendship never sinks.

I'm incredibly sorry something like this had to happen to you. I'm sure if you talk to all your friends about this and what happened, they'll understand. As said above, I suggest just making a new account with a new, completely different password.
As for the ban, I'm not sure how it banned you if the hacker was on another computer. Is there anyone else where you live or nearby that seems they could have done that? Or anybody who would have access to your computer?
Unfortunately, I don't allow anyone to get near to my computer at all and no one has access to it. Although I am scared, I wont let him/her get away with it. c:
