Here We Go Again....

Its another mother problem....

Being near her is like hell. She gets pissy over everything. Cant say or do anything without having my head bitten off :/ So yesterday, she asked me to get the mail from the mailbox, and at the time, she was just sitting on her ass. I was busy doing something, and said "I'll get it in a minute". She gets up, stomps outside, gets the mail, and yells at me. Like what the actual fuck?? It cant wait for one minute? ._.
Today, my boyfriend and I swam with dolphins, and it was awesome Of course when I get home, my mothers anger boils again for no apparent reason. I just sold my old bed, and got some cash for it. Mum needed some of it to pay for bills....yeah ok, I can deal with that. She's like "Can I have half??" A bill needed to be paid, so I said "How much if the bill??" Her response, "Im not telling you". You see, I wanted to know in case if it was a big bill. So she doesnt tell me, we have a staring competition, and she says, "You can get out and shove your money up your ass". Looooool, bitch please -_- Her and I got angry and I left. And she has the never to say I have an attitude problem -_-

What do you guys think?? I want to know that what I've done, is really nothing for my mother to get angry about

Sorry if I didnt make much sense, Im blinded with anger. She's become so rude to me since I got a boyfriend, she thinks everything revolves around her constantly :/ Its all about "What I want", not her husband, or her daughter....always about heeeeeer *rolls eyes*
