What To Do...What To Do...

I am in a dilemma..

I woke up at 5 am today and I cant stop thinking about going home. I am contemplating whether to go home in July for a month or in December for 3 months. I got a free return ticket this year so I'd like to use it to my advantage. If I go home in July, I wouldnt be going home in December and vice versa. Here are some pros and cons for going home in July (i.e staying in Aus for the summer holidays):

Pros:
I miss my family.
I miss the food there esp Nasi Katok *hehe*.
I might be able to see Bullet For My Valentine if they are coming later this year.
I can do a bit of travelling during summer.
There's nothing to do in Brunei so a month is enough.

Cons:
I wont be home for summer =(
Everyone is going home - double =(
I might get lonely during summer.
One month ticket is cheaper than 3 months ticket. My ticket is paid for, so why pick the cheaper one??
The next time I'd be going home is December next year.

I suppose I could go home later in December with my own money for a month but I really wanna save cos I might need the money for emergency use. I am going nuts here thinking about this all the time. Tell me your opinion.
