Hi there. I really need some help. I think my sister might have paranoia or Bipolar Disorder because she doesn't want me to speak to her when she's in a bad mood and when I try to start a conversation with her and then later on she comes over to me and starts trying to talk to me but I ignore her as that is because she did it to me in the first place. When she does this, she says she's sorry but she doesn't mean it because come another day, she does exactly the same thing. On the paranoid side, today, I had just got on the bus after school and she was already on it as she had been at another bus stop and I gave her packet of sweets that I'd bought just before I caught the bus. Then as I was eating mine, she told me to stop eating them. When I asked her why, she said it was because there were bullies on the bus, but I didn't exactly know there were any. I think she's paranoid because she thinks the bullies will notice if I am eating and that they'll pick on us. But then, later on, she starts to eat her sweets although she had agreed that we'd eat them at home and I couldn't eat mine as I knew she would say no. I feel as if I have no freedom and that I have to act a certain way just to satisfy her.
