To buy or not to?

ARGH.
I'm in a dilemma now.

Mum allows me to get a new camera.

BUT

YA says:
u really need tat camera izzit?
YA says:
or u just wana buy because u wana buy?

I do admit tt i just want to buy because i want to buy.
Because i want a new camera only.

The good side of me tells me not to, while the bad side of me says buy.

I have one Canon Ixus 55 with ONLY 5 megapixels, tt i'm using since sec4 yr end, and it's stil in a usable condition. (Just tt the screen is a lil spoilt, but i can see what i'm taking.)

And i have a DSLR Nikon D80 at home, waiting for me to use it. Cuz it's rotting in the dry box.
BUT i dun like to carry a DSLR with me as it's too heavy and bulky!

HOW
HOW
HOW?

Shucks.
I think i'm a good for nothing.
Good at spending money only.
DAMN
ME.
because i went shopping again today.
