Darkness overcomes me. Is this another obstacle for me in becoming an adult?

Im suppost to be going to Australia, having a ball with June and Prabs and my mum fucked it up for me. You know nowadays she's really a bitch from hell. I can't take it now. What happened? Well Prabs was suppost to buy tickets for me and her as well before Tuesday. I told my dad and he was cool about it but I totally forgot telling him about payment before Tuesday(I did mention about it but I didn't insist of the money). But he went overseas on friday so I couldn't ask him about the money. I told my mum about it and she said she can help me bank in some money. That was on Sunday(I went back to Kuantan for mothers day, lots of things to do, homework, preparation of mothers day, my car, etc). Then on Monday, I was terribly sick, trembling from cold and everything. I've spent most of the days sleeping, trying to recover fast before my class starts. Thank god my classes were cancelled that day. Mum and Prabz keep on calling but I just couldn't wake up after the pills I've taken. Then the next thing I know when I called my mum, she and my aunt discussed about the visa problem. Will I be able to get the visa after I bought the tickets? So I told Prabz and she said she will check the refund policy. Then she would call me around eleven. My mum told me to call her after knowing about the refund policy. I told her to bank in first to Prabz but she told me that she couldn't get enough money. Will bank in for me before tomorrow noon. Then I doze off to sleep with another pill. The next hour I woke up is around four in the morning. That would be too late to call Prabz nor my mum. So I thought I'd call them before noon. So I took another pill(still feeling sick but getting much better)and the next I woke up is around four pm again. Then Prabz called and mention the money isn't banked in yet and told me we can get the visa application and results straight away. I called my mum to ask about it. She said I haven't told her about the visa problem. I mentioned today is the last day to get cheap tickets.Anyway the flight tickets last a year right? If I can't go together with Prabz this time at least I can go any other time. She bitch me about me not doing things earlier and me always do things last minute. And she starts blabbing this and that. And the last sentence she did it. She said "I should have told dad that to never let you go". That did it.
Did she ever ask how sick I was? Did she ever ask why I was been sleeping for the whole day? All she did nowadays is getting obsessed with her direct selling. I know partially because she wanna earn more money for me to go to Australia and not worrying about the money part. Also she gets more friends and not just stuck to be a housewife which is like a living hell. But come on, she's not doing her job of a mother nowadays did she? She didn't even ask how was my progress of my life, my studies, NOTHING! She thought I was still the old Mandy. The one who don't give a fuck about the work. The one who does things slowly not thinking about other people. I did told her to enter the money to Prabz first just in case. And she said "I'm not rich, I can't suddenly find that much money", this that this that. They keep on denying it's partially their fault.
After arguing Karen is not enough, my mum HAS to argue with me. Dropping tons of weight on me.
