Need help please with a few questions

Please help me with a few questions? How would you say these?

1 You don't know what I'm going through/dealing with/experiencing. I've got my dad in the other room snoring so loud that no one can sleep. We can here it from our room. The only way we can get him to stop is if he snores loud enough to wake mother up. That way she can ask him to turn on his side.

Could you please help me with these?

- Try to overcome people's biases./prejudices.
- At the speed at which you're doing this, you'll still be on you're work tomorrow. (can you say BE ON IT?)
- What cup size are you/What's your cup size?
- Thats the phone number whose bill I paid. The other line is disconnected.
- I told him i was going to kick his butt, which is when he hung up.

thanks
