Angriest thing

I have being throwing tantrum since past month. Small room housemate is way too wasteful. I just received the bill today. And it's up to RM200 for almost 3 months!! What the hell? It is always around RM30. And now, I have to pay for the electricity and water that I have never use?? FML!! I don't know who to talk to. My Rm200 will be just gone like that. And still it does not include my rental. This is really disappointing. Heart is so pain. The middle room girl moved out last month. I called her to pay, she told me that she doesn't use that much of electricity and refuse to pay. What shall I do? I'm crying again. Sigh.
