You can stay, personally I did have fun playing with you several times, my objective is not to bully you, I want to make you change and quit doing certain things for everyone's sake. Do you really not see that you did something seriously wrong? On the other hand if mafia is making you cry for real or turns out to be bad for your health then you probably should stop playing indeed as it's not worth it. I have been in bad situations too, was angry or frustrated but I never actually cried because of a mafia round or had it affect my whole reallife.
Have to say, you already were at this point when you announced that you are leaving, making dramatic posts about it and then a few weeks or months later you showed up again as if nothing happened. I was worried about you and you know it, sis! But I really hope that this is not a way of emotional manipulation because I definitely wouldn't ppreciate being emotinally abused like that.
