Dad, again

I don't know what is wrong with my dad... he's always in trouble with his job. Now he's retrenched!
I really don't know what to say, except shaking my head in despair for him. What can I do? Why is he always down in luck! It happened once middle of this year he had a huge pay cut that saved him from losing his job. Now he lost it. Yes.
What do the whole family expect me to do? The only thing that is important is money, they value this far too much. Since a kid, I know nothing as much as close family ties... it was all about money, and now it is still money! I dislike it. I have a phobia of ringing them because they never gave me enough support till this day. Come home, come home, everything out of their mouth is about returning home. Why do they not see it? It's not fun, it's not a playground out here... this is how big the world is! This is about coming out on my own and realizing what I want to do with my life.
My sister is an A**hole, yes and I mean it now. She only wants to push part of the blame to me that she's shouldering everything now just because I left home. I'm not abandoning them, I don't understand how narrow-minded she is, she only sees that she's scared of handling it alone. How about me, have they give me all the assistance I needed out here?? When I was out in London alone, did they bother to call me and check on me? No... But they expect that much from me that I can't give.
I'm fed up about having a sister whom constantly makes me feel bad, feel guilty about home. Her sarcastic remarks and temper has provoked me so much that I can't be bothered to say nice things to her. She called me selfish, I asked her to look carefully whose selfish! I didn't leave home when it was in a bad state, and it happened when I'm here, I'm trying to look into it, but I don't feel encouraged at all - I'm beginning to be frightened about being stuck in Singapore!

Lord, oh Lord... am I borned in the wrong place with the wrong cultures...
